[Piglit] [PATCH 1/1] glsl: add explicit version 100 support

[Tom Gall]

This is a small change to add explicit support for glsl
version 100 which is used by OpenGL ES 2. This allows for
100 to be passed on the command line.

In glslparsertest.c add 100 to the list of versions processed
by the switch. Also when version 100 is used, check for gles
and if running as gles don't require the
GL_ARB_ES2_compatibility extension.

In CMakeList.gles2.txt remove ${OPENGL_gles2_LIBRARY} as it's
not needed.

v2: detach patch from proposed python change.
