Tests: adjusted TODO for OpenSSL 1.0.2h and up in h2_http2.t.

OpenSSL uses correct SNI/ALPN callback order (SNI callback before ALPN
callback) starting with OpenSSL 1.0.2h, so "sni to enabled" test
is expected to succeed starting with OpenSSL 1.0.2h.

With this change, the "openssl:..." feature test now supports checking
patch level encoded as letters, such as in "openssl:1.0.2h".
