[Piglit] [Patch v2 4/9] glsl_parser_test.py: Remove redundant StringIO creation

[Dylan Baker]

Previously the code read a StringIO, then immediately created a new one
to write the read text into. This is silly, by just setting the tell
back to position 0 the same effect can be had without the need to read
and write the contents.
