ecore animator, x, vsync ecore evas restore x vsync to work again

so i found the work with wayland and having animator sources broke
that same source from ecore_x that was there from long ago, so i've
put in an exception if there are x based engines from restting to a
timer animator because ecore_x would have switched toa custom ticker
already, and this just resets it. also just set the source after
setting the tick callbacks and ensure tick cb's are null before going
to timer source as well. this cleans up this little but of animaatior
vsync modification to properly vsync in both x and wayland too now.
