libssl: ensure server selected ALPN was advertised
Per RFC 7301, section 3.2, "In the event that the server supports no
protocols that the client advertises, then the server SHALL respond
with a fatal "no_application_protocol" alert.
If a server does not do that and chooses a protocol that we have not
advertised, we should abort the handshake. The RFC does not specify
an alert for this case. BoringSSL chose illegal_parameter and OpenSSL
decode_error. I slightly prefer illegal_parameter, so went with that.
Reported by Acts1631 with a similar diff.
