[PATCH v2 2/4] tst-fopen-threaded.c: Delete temporary file

[H.J. Lu]

Update tst-fopen-threaded.c to call support_create_temp_directory to
create a temporary directory and open "file" in the temporary directory,
instead of using /tmp/openclosetest and leaving it behind.

This partially fixes BZ #33182.
