Fix OCSP tests on Fedora and derivatives. It turns out we were signing OCSP

responses with SHA-1, which is disabled in OpenSSL builds on those platforms.

In addition, perform three *headbang*s for not catching this when I refreshed
the test certificates to also not use SHA-1. My wall is now slightly dented.

* test/test_ssl.c
  (create_ocsp_response): Use EVP_sha256() instead of EVP_sha1().
