test-sha1: Add test vectors from RFC 6070

The test with very large iterations count is commented out since it
takes quite long to derive (it does pass, though). In addition, the
last test vector is commented out since pbkdf2_sha1() does not support
arbitrary binary passphrases (\0 inside the string).
