g10: Fix --list-packets.

* g10/gpg.c (main): Call set_packet_list_mode after assignment of
opt.list_packets.
* g10/mainproc.c (do_proc_packets): Don't stop processing with
--list-packets as the comment says.
* g10/options.h (list_packets): Fix the comment.
* g10/parse-packet.c: Fix the condition for opt.list_packets.
