[Piglit] [PATCH v2 3/3] framework/test/glsl_parser_test.py: allow forcing the desktop version

[baker.dylan.c at gmail.com]

From: Dylan Baker <baker.dylan.c at gmail.com>

This adds a new environment variable, PIGLIT_FORCE_GLSLPARSER_DESKTOP,
which forces glsl_parser_test.py to use "glslparsertest" for GLES tests
(instead of "glslparsertest_gles2").

This could be used to force testing ES_<ver>_compatibility extensions
even when OpenGL ES tests are being built.
