selftests: xsk: Implement bpf_link test
Introduce a test that is supposed to verify the persistence of BPF
resources based on underlying bpf_link usage.
Test will:
1) create and bind two sockets on queue ids 0 and 1
2) run a traffic on queue ids 0
3) remove xsk sockets from queue 0 on both veth interfaces
4) run a traffic on queues ids 1
Running traffic successfully on qids 1 means that BPF resources were
not removed on step 3).
In order to make it work, change the command that creates veth pair to
have the 4 queue pairs by default.
Introduce the arrays of xsks and umems to ifobject struct but keep a
pointers to single entities, so rest of the logic around Rx/Tx can be
kept as-is.
For umem handling, double the size of mmapped space and split that
between the two sockets.
Rename also bidi_pass to a variable 'second_step' of a boolean type as
it's now used also for the test that is introduced here and it doesn't
have anything in common with bi-directional testing.
Drop opt_queue command line argument as it wasn't working before anyway.
