On non-Apple Internal machines with System Integrity Protection enabled, run-webkit-tests fails to create the user's cache directory with suffix DIRHELPER_USER_DIR_SUFFIX because the path returned by os.confstr(65538) [1] does not include the suffix as confstr(3) only honors DIRHELPER_USER_DIR_SUFFIX for privileged processes when System Integrity Protection is enabled on non Apple-Internal machines.
