[PATCH 1/7] kdf: Skip tests if hash algo is not available

[Clemens Lang]

* tests/t-kdf.c (check_openpgp, check_pbkdf2): Test digest availability.

--

Skip tests that would fail if libgcrypt is compiled with an
--enable-digests option that does not include the required digest
algorithms for the test vectors.
