Tests: adjusted stream_ssl_alpn.t to handle old SSL libraries. The "ssl_alpn" directive of the stream module requires an SSL library with ALPN support, and startup fails if the directive is used in the configuration but ALPN support is not available (notably, with OpenSSL before 1.0.2). Restored try_run() to skip the test in this case.
