input: switch hid keyboard to new input layer api.

Browse source 
Minimal patch to get the switchover done.  We continue processing ps/2
scancodes for now as they are part of the live migration stream.  Fixing
that, then mapping directly from QKeyValue to HID keycodes is left as
excercise for another day.
