[PATCH:oclock] Enable the latent XKBStdBell code in oclock

[Alan Coopersmith]

This code has been unreachable since the switch from Imake lost -DXKB,
might as well hook it back up.   Sadly it relies on the nonsensical use
of libxkbfile for the Bell calls, but such is the state of our XKB Bell API.
