send wl_touch events when we handle mouse buttons

Small patch to enable sending wl_touch down/up events when pointer
mouse button events are handled. This is needed in the case where we
do Not have any mouse pointer at all, but we do have touch support.

ref T5094

NB: This allows weston-simple-touch client to operate in Enlightenment
now. There is still something strange happening with EFL clients in E
wrt touch events tho...
