[PATCH 1/2 xorg-gtest] Add comment to Makefile-xorg-gtest.am about compiling with -w

[Chase Douglas]

Users of xorg-gtest will not want warnings or failed builds due to
issues in gtest or xorg-gtest.

Note that the internal build of the xorg-gtest example does not use the
-w flag when building examples, so we will still see warnings when
xorg-gtest itself is built.
