selftests: netfilter: nft_queue.sh: fix spurious timeout on debug kernel
The sctp selftest is very slow on debug kernels. Its possible that the nf_queue listener program exits due to timeout before first sctp packet is processed. In this case socat hangs until script times out. Fix this by removing the -t option where possible and kill the test program once the file transfer/socat has exited. -t sets SO_RCVTIMEO, its inteded for the 'ping' part of the selftest where we want to make sure that packets get reinjected properly without skipping a second queue request. While at it, add a helper to compare the (binary) files instead of diff. The 'diff' part was copied from a another sub-test that compares text. Let helper dump file sizes on error so we can see the progress made. Tested on an old 2010-ish box with a debug kernel and 100 iterations. This is a followup to the earlier filesize reduction change.
