hwc: rgz: Fix for pixel wide regions returning no ops

A region that is pixel wide is in the top-left corner of the screen
(0,0,1,1) makes the empty_rect function to return true, which
is wrong since the region is not an empty rectangle.

Since this function is being used in the moment the blits are
generated, the regionizer thinks the region is empty with no
intersections leading to error messages.
