mod_tls: Set ALPN on outgoing connections
Relevant and sometimes needed for Direct TLS which mod_s2s uses this
context for. Primarily when e.g. mod_net_multiplex or equivalent ALPN
based dispatch is used.
All these contexts should likely move away from mod_tls and into either
mod_s2s or portmanager. The later already duplicates some of this work.
