[Piglit] [PATCH 2/2] tests/py_modules/constants.py: make dosify function return unicode

[Dylan Baker]

This also got missed in the big unicode conversion. subprocess.Popen
(and it's wrappers like check_output) return bytes, but the module
expects UTF-8 unicode. This fixes that by decoding the output
appropriately.
