gpg: Implement keybox compression run

Browse source 
* kbx/keybox-init.c (keybox_lock): Add arg TIMEOUT and change all
callers to pass -1.
* g10/keydb.c (keydb_add_resource): Call keybox_compress.
--

Note that here in the 2.2 branch the way we call the locking in gpgsm
is different from the one in gpg.  So we could not cherry-pick from
master.
