the check for null signatures should be done by the caller not the callee.

It might be acceptable for mono_signature_get_desc since this is a debug
helper, but it should return a canonical string pointing to this fact.

Making mono_metadata_signature_equal accept NULL signatures will only help
hiding real bugs.

Unfortunately, the way to fix this is to check all callers of
mono_method_signature for what to do on failure.
