[Piglit] [PATCH] tests: fix unicode issue on MinGW in find_static_tests.py

[Brian Paul]

Explicity convert strings to unicode before writing.
This fixes an error when building with MinGW:
Traceback (most recent call last):
  File "/var/workspace/tests/find_static_tests.py", line 74, in <module>
    main()
  File "/var/workspace/tests/find_static_tests.py", line 69, in main
    f.write(filename)
TypeError: write() argument 1 must be unicode, not str
