Remove the wait for the ibus daemon to start

Browse Source 
The initial implementation of Uinicode input via IBus used a startup delay
of 3 seconds to wait for the daemon to be ready before connecting to it.

This commit introduces a poll-wait loop which can remove the delay
entirely if the daemon is up when chansrv starts the interface.
