clock: ensure launch is listening correctly

Browse Source 
In the wild, ships that were live pre-OS1 still had launch subscriptions
open to the clock on the /tile path, instead of the currently-used
/clocktile path. Additionally, launch state for the clock tile seemed
incomplete.

Here, we simply re-%add the clock to launch.

Note that launch currently does not clean up old subscriptions on
path change. For the pre-OS1 case, the old path is no longer in use,
rendering the subscription harmless. For cases where the correct
subscription was already in place, it'll print a %watch-wire-not-unique,
but doesn't do any harm besides that.
