System FIPS mode check is no longer dependent on /etc/system-fips file. The change should be compatible with older distributions since we now depend on crypto backend internal routine. This commit affects only FIPS enabled systems (with FIPS enabled builds). In case this causes any regression in current distributions feel free to drop the patch. For reference see https://bugzilla.redhat.com/show_bug.cgi?id=2080516
