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.
