selftests/bpf: move SYS() macro into the test_progs.h
...
A lot of tests defined SYS() macro to run system calls with goto label.
Let's move this macro to test_progs.h and add configurable
"goto_label" as the first arg.

selftests/bpf: Don't refill on completion in xdp_metadata
...
We only need to consume TX completion instead of refilling 'fill' ring.
It's currently not an issue because we never RX more than 8 packets.

selftests/bpf: Fix unmap bug in prog_tests/xdp_metadata.c
...
The function close_xsk() unmap via munmap() the wrong memory pointer.
The call xsk_umem__delete(xsk->umem) have already freed xsk->umem.
Thus the call to munmap(xsk->umem, UMEM_SIZE) will have unpredictable
behavior that can lead to Segmentation fault elsewhere, as man page
explain subsequent references to these pages will generate SIGSEGV.
