bpf: selftests: send packet to devmap redirect XDP
The current xdp_devmap_attach test attaches a program
that redirects to another program via devmap.
It is, however, never executed, so do that to catch
any bugs that might occur during execution.
Also, execute the same for a veth pair so that we
also cover the non-generic path.
Warning: Running this without the bugfix in this series
will likely crash your system.
