gpg: Fix --rebuild-keydb-caches.

Browse source 
* g10/parse-packet.c (parse_key): Store even unsupported packet
versions.
* g10/keyring.c (keyring_rebuild_cache): Do not copy keys with
versions less than 4.
--

That function, which is implicitly called while checking the keydb, led
to corruption of v3 key packets in the keyring which would later spit
out "packet(6)too short" messages.
