When Dracut starts up, it needs to determine whether a pool will remain
"hanging open" before the system shuts off. In such a case, then the
code to clean up the pool (using the previous export -F work) must
be invoked. Since Dracut has had a recent change that makes
mount-zfs.sh simply not run when the root dataset is already mounted,
we must use the cleanup hook to order Dracut to do shutdown cleanup.
Important note: this code will not accomplish its stated goal until this
bug is fixed: https://bugzilla.redhat.com/show_bug.cgi?id=1385432
That bug impacts more than just ZFS. It impacts LUKS, dmraid, and
unmount during poweroff. It is a Fedora-wide bug.

Closes#5287
Based upon @ryao's initial fix for 1c73494394fc9de9283b3fd4f00bcdf4bd300a7
( 5e9843405f63fdabe76e87b92b81a127d488abc7 ) this one also uses
`command -v` instead of `type`, but additionally only applies the
fix to close zfsonlinux/zfs#4749 when `libgcc_s.so.1` has not been included
by dracut automatically (verified by whether `zpool` links directly to
`libgcc_s.so`), as well as change the fallback option to match `libgcc_s.so*`.

Closes#5089Closed#5138
- In older systems without sysroot.mount, import before dracut-mount,
and re-enable old dracut mount hook
- rootflags MUST be present even if the administrator neglected to
specify it explicitly
- Check that mount.zfs exists in sbindir
- Remove awk and head as (now unused) requirements, add grep, and
install the right mount.zfs
- Eliminate one use of grep in Dracut
- Use a more accurate grepping statement to identify zfsutil in rootflags
- Ensure that pooldev is nonempty
- Properly handle /dev/sd* devices and more
- Use new -P to get list of zpool devices
- Bail out of the generator when zfs:AUTO is on the root command line
- Ignore errors from systemctl trying to load sysroot.mount, we only
care about the output
- Determine which one is the correct initqueuedir at run time.
- Add a compatibility getargbool for our detection / setup script.
- Update dracut .gitignore files

Dracut and Systemd updated how they integrate with each other, because
of this our current integrations stopped working (around the time
4.1.13 came out). This patch addresses that issue and gets us booting
again.
Thanks to @Rudd-O for doing the work to get dracut working again and
letting me submit this on his behalf.

The dracut code is analogous to the initramfs code and as such
it should be located in the contrib with initramfs for consistency.
