====================
Fix broken TC_ACT_REDIRECT from qdiscs

This is an alternative fix to [0] in order to not uglify
__dev_queue_xmit() with sprinkled ifdefs given this can be
simplified and isolated through a simple test into the BPF
redirect helper itself.

I've also added a proper BPF selftest, so there is no need
to check-in a binary BPF object into selftests given we do
have BPF infra for all of this.
