selftests/xsk: Add packet stream replacement function
Add pkt_stream_replace_ifobject function to replace the packet stream for
a given ifobject.
Enable separate TX and RX packet replacement, allowing RX side packet
length adjustments using bpf_xdp_adjust_tail() in the upcoming patch.
Currently, pkt_stream_replace() works on both TX and RX packet streams,
and this new function provides the ability to modify one of them.
