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.
