The test-18-options.fstab.input scenario was guarded by
"$(readlink /mnt)" != "/mnt", which is true on any normal system
since readlink prints nothing for a plain directory. This meant the
scenario was always skipped, and its fixtures were never actually
compared against generator output.
Fix the guard to check whether /mnt is a symlink directly, and repair
the pre-existing fixtures that had drifted while the scenario was
dead:
- mnt-wantedby-automount.mount had a stale Where= value and was
missing the escaping the generator emits for the hyphen in
/mnt/wantedby-automount.
- mnt-requires.mount had Requires=/After= in the wrong order.
Also extend the backslash-stripping workaround loop (used because the
.deb packager dislikes files named with a backslash) to cover
.automount units in addition to .mount/.swap, and fix an ordering bug
where -f was checked before -L, which could leave a dangling symlink
when both a unit and its drop-in symlink needed stripping.
On rpm-ostree distributions such as Fedora SilverBlue /mnt
(and other well known paths) will be a symlink to a location
under /var. The fstab generator emits correct output in this
case, however, the data does not match the expected output
stored in the source tree.
Rather than trying to adapt the test data, just skip this
single test scenario when we see /mnt is a symlink.

Dangling symlinks get pruned when packaging up the installation
directory. Just store empty files instead, and compare the names
rather than the content for .requires/.wants - the filename is
what is important anyway, the content is ignored.
