autotest (wifi): ensure footer data is written to disk

In SiteLinuxRouter._prep_probe_response_footer(), we write()
to a file, and then send_file() over to the router.

The problem is that Python buffers write()s. So, when send_file()
tries to read the data, it may still be stuck in a buffer inside
the Python process.

Fix this, by calling flush() before send_file().
