Libguestfs - May 2022 - [libguestfs PATCH] generator/customize: reintroduce "--selinux-relabel" as a compat option

Removing "--selinux-relabel" in commit 2f6a27f1077d
("generator/customize:
invert SELinux relabeling default", 2022-05-11) breaks existing scripts
that invoke virt-customize and/or virt-sysprep with that option. Restore
the option, with no functionality tied to it.

Fixes: 2f6a27f1077d32d1ab526427052fc88e188356f7
Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2089748
