gpg: Do not bail out on secret keys with an unknown algo

Browse Source 
* g10/getkey.c (lookup): Skip keys with unknown algos.
--

If the local store has private keys with an algorithm not supported by
thi version of gpg, gpg used to bail out.  Thus decryption of proper
messages was not possible.  This fix skips such secret keys.
