Hoist loading default root certificates into ircConfig()
tls_connect_socket(3) in ircConnect() does that by default already
unless tls_config_set_ca_file(3) was used.

Loading CA certificates before connecting makes no practical difference
except on OpenBSD where this allows for tighter unveil und pledge setups
now that all required (TLS related) file I/O is finished by the time
ircConnect() gets to do network I/O.

In case of the hidden `-!' insecure flag which is implied by `-o' to
print server certificates and exit, loading root certificates is not
required at all;  likewise, using explicit self signed server
certificates will not involve certificate authorities either, hence load
them only if needed.
