This is broken if run-tests.sh is not invoked inside
tests/shell, I've fixed this up.

Meanwhile I added probe for netdev-chains-without-device and SKIPPED
support:

I: [OK]         ././testcases/chains/0044chain_destroy_0
I: [SKIPPED]    ././testcases/chains/netdev_chain_0
I: [OK]         ././testcases/comments/comments_0

My plan is to keep adding more probe files locally until ./run-tests.sh
passes on 5.14-patched-kernel and then send the batch.

I've also changed the probe files to contain the upstream patch
and its upstream kernel version as a comment.
