[Piglit] [PATCH 5/6] framework: observe PIGLIT_NO_FAST_SKIP in ShaderTest::__init__()

[Brian Paul]

If PIGLIT_NO_FAST_SKIP is defined, the FastSkip/FastSkipMixin classes
are no-ops.  Therefore, the GL/GLSL version info collected in
ShaderTest::__init()__ isn't used.  Skipping the shader test parsing
is a big win for reducing start-up time on Windows.  There's not much
difference either way on Linux.
