[Piglit] [PATCH] tests/py_modules/constants.py: look for generated_tests in build dir

[Brian Paul]

If piglit is built out of source (such as in a top-level build/ directory),
the generated shader tests will be in build/generated_tests/.  This patch
checks if PIGLIT_BUILD_DIR is set, and if so, looks for generated_tests/ in
that directory.
