libio: Update tst-wfile-sync to not depend on stdin
The test expects stdin to be a file which is not the case when running tests over ssh where stdin is piped in. The test fails with: error: xlseek.c:27: lseek64 (0, 0, 1): Illegal seek Update the test to create a temporary file and use that to perform the test.
