exec/tests/ircd/lib.sjs
Log Message:
ircd tests: bind the test IRCd to the loopback address only

Every test in exec/tests/ircd failed on Linux with "port not ready
after 5s". lib.sjs started the IRCd without -a, so Startup() fell back
to its ["0.0.0.0", "::"] default and tried to bind both. Where net.ipv6.bindv6only is 0 -- the default on Linux -- the "::" socket is dual-stack and collides with the 0.0.0.0 one already bound, so the
second bind failed with EADDRINUSE and no listener came up at all:

!ERROR 98 binding IRCd socket: Address already in use
!Error Error: Unable to add host to socket set

Pass -a with the address the tests actually connect to. They only ever
talk to IRCD_TEST_HOST, so binding the wildcards was never needed.
