[PATCH xf86-video-vmware] Use dixLookupWindow instead of LookupWindow on Xorg 1.5 & later

[Alan Coopersmith]

The LookupWindow function was deprecated in xserver commit ed75b056511ccb4
and removed during the Xorg 1.11 merge window by commit 82a8677d9175732.

Needed for compatibility with the Xorg 1.11 release - only build tested
with Xorg 1.11.1, but I tried to preserve compatibility with older releases,
following the current status quo of this driver, while making it simple to
drop that when it's no longer needed.
