sys/linux: cover live packet mode for BPF_PROG_RUN
Commit [1] upstream added a new mode for the BPF command BPF_PROG_RUN
when used with XDP program (type BPF_PROG_TYPE_XDP). This new mode
allows injecting packets to the network stack after they have been
processed by the test BPF program.
This new mode expects specific arguments. Specifically, only the
BPF_F_TEST_XDP_LIVE_FRAMES flag is accepted and data_out & ctx_out must
be NULL.
