Fix VerifyPeerCertMatchesHost tests.

The original test did not properly test the bugs it fixed (SAN vs. CN)
and violated BoringSSL invariants:

- That SSL_get_peer_certificate works on the pending session before the
  handshake is a weird OpenSSL quirk that may later get fixed in
  BoringSSL. Calling code should not rely on this.

- SSL_SESSION is a private struct and may not be accessed directly by
  callers.

- Caller especially may not mutate private structs. The tests did not
  keep the SSL_SESSION's X509 and CRYPTO_BUFFER fields in sync.

Instead, make an actual connected SSL object and better test the SAN vs.
CN case.
