glamor: Adjust for drawable x/y in composite's copy optimization

Browse Source 
Patch b64108fa30 added a short cut that
identifies composite operations that can be performed with a simple
copy instead.

glamor_copy works in absolute coordinates, so the dx and dy values
passed in need to be converted from drawable-relative to absolute by
adding the drawable x/y values.
