bpf: Support specifying ingress via xdp_md context in BPF_PROG_TEST_RUN
Support specifying the ingress_ifindex and rx_queue_index of xdp_md
contexts for BPF_PROG_TEST_RUN.
The intended use case is to allow testing XDP programs that make decisions
based on the ingress interface or RX queue.
If ingress_ifindex is specified, look up the device by the provided index
in the current namespace and use its xdp_rxq for the xdp_buff. If the
rx_queue_index is out of range, or is non-zero when the ingress_ifindex is
0, return -EINVAL.
