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.

The fread race checker looks for EOF in every thread, which is incorrect
since threads calling fread successfully could lag behind and read the
EOF condition, resulting in multiple threads thinking that they
encountered an EOF.
Only look for EOF condition if fread fails to read a char. Also drop
the clearerr() since it could mask the failure of another reader, thus
hiding a test failure.
Finally, also check for error in the stream for completeness.
