Perform TLS handshake after final pledge
ircConnect() yields a connected TCP socket after which "inet dns" is
no longer needed.

Possibly having loaded private key material, it seems a tad more
comforting to speak TLS *after* dropping any network capabilities
(except for socket read/write to the IRC host, of course).

Instead of moving the final pledge into irc.c:ircConnect() and thus
complicating the code around pledge across two C modules, simply
stub out an mnemonic ircHandshake() and call that explicitly.

This restores behaviour gained with
981ebc4 "Remove explicit tls_handshake(3) from ircConnect" which
was reverted for other reasons.
