[Piglit] [PATCH] util/gl: Change default waffle platform

[Chad Versace]

Change default waffle platform from GLX to XEGL for GLES tests.

The default platform was GLX for all GL tests (GL and GLES).  But not all
GLX implementations support creation of ES1 and ES2 contexts. Unless the
user explicitly set PIGLIT_PLATFORM to some EGL platform, this problem
caused GLES tests to skip.

Enables 76 GLES tests on my system.
