xkb: use GPE for XKB fake motion events. 

Section 4.6.1 of the XKB spec says that "the initial event always moves the
cursor the distance specified in the action [...]", so skip the
POINTER_ACCELERATE flag for GPE, it would cause double-acceleration.

Potential regression - GPE expects the coordinates to be either relative or
both. XKB in theory allows for x to be relative and y to be absolute (or
vice versa). Let's pretend that scenario has no users.
