gpg: Avoid output to the tty during import.

Browse Source 
* g10/key-check.c (key_check_all_keysigs): Add arg mode and change all
output calls to use it.
* g10/keyedit.c (keyedit_print_one_sig): Add arg fp and chnage all
output calls to use it.
(keyedit_menu): Adjust for changes.
* g10/gpgcompose.c (keyedit_print_one_sig): Add dummy arg fp.
* g10/import.c (import_one): Call key_check_all_keysigs with output to
the log stream.
