selftests, xsk: Fix bpf_res cleanup test
After commit 710ad98c363a ("veth: Do not record rx queue hint in veth_xmit"),
veth no longer receives traffic on the same queue as it was sent on. This
breaks the bpf_res test for the AF_XDP selftests as the socket tied to
queue 1 will not receive traffic anymore.
Modify the test so that two sockets are tied to queue id 0 using a shared
umem instead. When killing the first socket enter the second socket into
the xskmap so that traffic will flow to it. This will still test that the
resources are not cleaned up until after the second socket dies, without
having to rely on veth supporting rx_queue hints.
