faefd29 qa: Prepare functional tests for Windows (MarcoFalke)

Pull request description:

  * Pass `sys.executable` when calling a python script via the subprocess
    module
  * Don't remove the log file while it is still open and written to
  * Properly use os.pathsep and os.path.sep when modifying the PATH
    environment variable
  * util-tests: Use os.path.join for Windows compatibility
