[PATCH weston] evdev: write EV_SYN input_event along with led events to device

[Rolf Morel]

Other clients of an evdev device need to have the events they receive
be separated, in moment in time, from other events by an EV_SYN/
SYN_REPORT. This is the responsibility of the client who writes events
into the stream.
