Closes#12101
Commit 109d2c9310 ("Move zfs_gitrev.h to build directory") stopped
distributing zfs_gitrev.h, as it is a generated file. Add it back, with
some changes in behavior.
Change the logic for gitrev as follows
- if the source tree is a git repository, the behavior for build is
unchanged. For make dist, append -dist to the git tag in the
distributed version of zfs_gitrev.h.
- otherwise, check if the source tree contains zfs_gitrev.h, and use it
if so, falling back to "unknown" if it doesn't exist.
- clean it only in make maintainer-clean, so we don't remove it from the
source tree on make clean or make distclean.
This allows disted sources to track what git tag they originally came
from, with the -dist suffix indicating that the code wasn't built
directly from git and so might contain additional changes beyond the git
tag.

Commit 109d2c9310 ("Move zfs_gitrev.h to build directory") removed
scripts/make_gitrev.sh, putting the logic into the Makefile itself.
However, at least the Arch Linux packager wants the script so that the
file can be generated without having to run configure first, for
DKMS packaging purposes.
So move the make recipe back into the script.

Closes#10595
Currently an out-of-tree build does not work with read-only source
directory because zfs_gitrev.h can't be created. Move this file to the
build directory, which is more appropriate for a generated file, and
drop the dist-hook for zfs_gitrev.h. There is no need to distribute this
file since it will be regenerated as part of the compilation in any
case.
scripts/make_gitrev.sh tries to avoid updating zfs_gitrev.h if there has
been no change, however this doesn't cover the case when the source
directory is not in git: in that case zfs_gitrev.h gets overwritten even
though it's always "unknown". Simplify the logic to always write out a
new version of zfs_gitrev.h, compare against the old and overwrite only
if different. This is now simple enough to just include in the
Makefile, so drop the script.

In some build methods, the gitrev is unnecessarily set to "unknown".
We can improve this by changing the gitrev to use
`git describe --always --long --dirty`.
This gets the revision even when no tag matches (--always). It prints
the hash even when it exactly matches a tag (--long). And if there are
uncommitted changes, it appends "-dirty", rather than failing (--dirty).

`scripts/make_gitrev.sh` had 'set -e' so if any command failed it would
fail and cause copy-builtin to fail (copy-builtin also has `set -e`.
This commit also simplifies scripts/make_gitrev.sh to always write a
file by using a cleanup function. It also simplifies other areas of
the script as well (making it much shorter).

The existing mechanisms for determining what code is running in the
kernel do not always correctly report the git hash. The versions
reported there do not reflect changes made since `configure` was run
(i.e. incremental builds do not update the version) and they are
misleading if git tags are not set up properly. This applies to
`modinfo zfs`, `dmesg`, and `/sys/module/zfs/version`.
There are complicated requirements on how the existing version is
generated. Therefore we are leaving that alone, and adding a new
mechanism to record and retrieve the git hash:
`cat /proc/sys/kernel/spl/gitrev`
The gitrev is re-generated at compile time, when running `make`
(including for incremental builds). The value is the output of `git
describe` (or "unknown" if not in a git repo or there are uncommitted
changes).
We're also removing /proc/sys/kernel/spl/version, which was never very
useful.
