Remove FIPS mode test

FIPS mode is currently broken in both Fedora rawhide and RHEL 10. This
test is no longer useful because it's now testing whether GnuTLS works
rather than whether GLib works.

-This will test a few problems that we hit recently:
+These are expected to be broken, depending on system crypto policy,
-
+which may disable the algorithms.
-g_hmac_copy() is broken, https://bugzilla.redhat.com/show_bug.cgi?id=1786538
-
-Crash in g_hmac_update() in FIPS mode, https://bugzilla.redhat.com/show_bug.cgi?id=1971533
-
-Crash when passing -1 length to g_hmac_update() (discovered in #1971533)
-
-We'll also test to ensure MD5 fails, and stop compiling the other MD5
-tests.
