gpg-interface.c: support getting key fingerprint via %GF format
Support processing VALIDSIG status that provides additional information
for valid signatures. Use this information to propagate signing key
fingerprint and expose it via %GF pretty format. This format can be
used to build safer key verification systems that verify the key via
complete fingerprint rather than short/long identifier provided by %GK.
