gpg: Avoid superfluous sig check info during import.

* g10/key-check.c (print_info): New.
(key_check_all_keysigs): Print sig checking results only in debug
mode.  Prettify the stats info and suppress them in quiet mode.

--

This also makes usable stats by prefixing them with the key and the
program name.
