kbx: Let keydb_search skip unwanted blobs.

Browse Source 
* kbx/keybox.h (keybox_blobtype_t): New.
* kbx/keybox-defs.h (BLOBTYPE_*): Replace by KEYBOX_BLOBTYPE_*.
* kbx/keybox-search.c (keybox_search): Add arg want_blobtype and skip
non-matching blobs.
* sm/keydb.c (keydb_search): Pass KEYBOX_BLOBTYPE_X509 to keybox_search.
* g10/keydb.c (keydb_search): Pass KEYBOX_BLOBTYPE_PGP to keybox_search.
--

Without this fix a listing of all keys would fail because the wrong
blob type would be returned for the gpg or gpgsm.
