crypto: api - crypto_alg_mod_lookup either tested or untested

As it stands crypto_alg_mod_lookup will search either tested or
untested algorithms, but never both at the same time.  However,
we need exactly that when constructing givcipher and aead so
this patch adds support for that by setting the tested bit in
type but clearing it in mask.  This combination is currently
unused.
