MODSIGN: Add FIPS policy
If we're in FIPS mode, we should panic if we fail to verify the signature on a module or we're asked to load an unsigned module in signature enforcing mode. Possibly FIPS mode should automatically enable enforcing mode. Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
