common,gpg: Fix processing of search descriptions ending in '!'.

Browse Source 
* g10/gpg.c (check_user_ids): If the search description describes a
keyid or fingerprint and ends in a '!', include the '!' in the
rewritten description.
* common/userids.c (classify_user_id): Accept keyids and fingerprints
ending in '!'.
