Previously, we'd attempted to detect OpenSSL without actually importing, in order to avoid a runtime penalty for importing `oauth2client`. However, in some exotic situations, `imp.find_module` can fail even though the import would be successful. We tweak to fall back to importing, and add some gross to the corresponding test.
