[ruby/openssl] test/openssl/test_ssl: assume ECC support

Disabling ECC support of OpenSSL is impractical nowadays.

We still try to have the C extension compile on no-ec builds (as well
as no-dh or no-engine, etc.) as long as we can, but keeping test cases
for such an extreme scenario is not worth the effort.
