selftests/bpf: Migrate test_xdp_meta.sh into xdp_context_test_run.c

Browse Source 
test_xdp_meta.sh can't be used by the BPF CI.

Migrate test_xdp_meta.sh in a new test case in xdp_context_test_run.c.
It uses the same BPF programs located in progs/test_xdp_meta.c and the
same network topology.
Remove test_xdp_meta.sh and its Makefile entry.
