gpg: Try Signer's User ID sub-packet with --auto-key-retrieve.

Browse source 
* g10/packet.h (PKT_signature): Add field 'signers_uid'.
* g10/parse-packet.c (parse_signature): Set this field.
* g10/free-packet.c (free_seckey_enc): Free field.
(copy_signature): Copy field.
* g10/mainproc.c (akl_has_wkd_method): New.
(check_sig_and_print): Extend NEWSIG status.  If WKD is enabled try to
locate a missing key via the signature's Signer's User ID sub-packet.
Do this right before trying a keyserver lookup.
