check_interface_method_override fix

Making mono_metadata_signature_equal work with NULL signatures can cause
unknown problems for the runtime such as ill constructed vtables. It fixes a
lot of crashes but opens the door for a lot of unknown issues.

The attached patch fixes check_interface_method_override which might be enough
for this bug in particular.

What about fixing all the mono_method_signature issues as we find them?

Please review the patch.
