[RHEL-9] fips-mode-setup: more thorough --disable, still unsupported
A RHEL-9 version of !147 (merged).
Differences:
-
/etc/system-fips
is being created and removed on 9, while on Fedora it's no longer there -
fips-finish-install(8)
manpage now states the file has been deprecated (I think previously it was in release notes only)
