Update inputproto to 2.3.2.

Two fixes to the specs (i.e. text-file only). And Andreas' patch fixes up
our asciidoc output to provide consistent output on rebuilds.

Andreas Boll (1):
      specs: Set TZ=UTC before calling asciidoc

Peter Hutterer (3):
      specs: note the (unused) time field in XIPassiveGrabDevice
      specs: rename EVENTMASK to EVTYPEMASK
      inputproto 2.3.2
