dix: only allow button and key events to freeze a sync'd pointer 

If a client calls XAllowEvents(SyncPointer) it expects events as normal until
the next button press or release event - that freezes the device. An e.g.
proximity event must thus not freeze the pointer.

As per the spec, only button and key events may do so, so narrow it to these
cases.
