A common usage pattern for zgenhostid, including in the ZFS dracut
module, is running it as:
zgenhostid $(hostid)
However, zgenhostid only accepted hostid arguments greater than 0, which
meant that, when the output of hostid(1) was "00000000", zgenhostid
would error out, even though 0 is a possible return value for the
gethostid(3) function used by hostid(1):
- On current musl libc, gethostid(3) is a stub that always returns 0.
- On glibc, gethostid(3) will return 0 if /etc/hostid exists but is
smaller than 4 bytes.
In these cases, it makes more sense for zgenhostid to treat a value of 0
as other parts of the zfs codebase do, meaning that a hostid value
couldn't be determined; therefore, it should attempt to generate a
random value to write into /etc/hostid.
The manpage and usage output have been updated to reflect this.
Whitespace has also been fixed in the usage output.

It was discovered that dracut scripts and zgenhostid
always generate little-endian /etc/hostid.
This commit provides simple endianess-aware binary
and updates the scripts to use it.
New features include:
-f flag to force overwrite.
-o flag to write to different file (for dracut)
accepting both 0x01234567 and 01234567 values as input
