gpg: When comparing keyids, use the keyid, not the fingerprint's suffix.

Browse Source 
* g10/keyedit.c (menu_select_key): Use spacep and hexdigitp instead of
inline tests.  Don't compare P to the suffix of the fingerprint.  If P
appears to be a keyid, do an exact compare against the keyid.  If it
appears to be a fingerprint, do an exact compare against the
fingerprint.
