Socket: make setTimeout catch errors.

setTimeout may be called as a supybot.drivers.poll callback,
which may by the access to supybot.drivers.poll() in _select;
so a crash in setTimeout will propage up to _run(), which would
cause a random driver to be killed because another one failed
and that's bad.

For example:

INFO 2020-05-27T18:40:18 supybot Received SIGHUP, reloading configuration.
ERROR 2020-05-27T18:40:19 supybot Uncaught exception in in drivers.run:
