selftests: Add use case section to fcnal-test

Add use case section to fcnal-test.

Initial test is VRF based with a bridge and vlans. The commands
stem from bug reports fixed by:

a173f066c7 ("netfilter: bridge: Don't sabotage nf_hook calls from an l3mdev")
cd6428988b ("netfilter: bridge: Don't sabotage nf_hook calls for an l3mdev slave")
