0bfb95f59a selftests, bpf: Do not yet switch to new libbpf XDP APIs 
Revert commit 544356524d ("selftests/bpf: switch to new libbpf XDP APIs")
for now given this will heavily conflict with 4b27480dca ("bpf/selftests:
convert xdp_link test to ASSERT_* macros") upon merge. Andrii agreed to redo
the conversion cleanly after trees merged.

544356524d selftests/bpf: switch to new libbpf XDP APIs 
Switch to using new bpf_xdp_*() APIs across all selftests. Take
advantage of a more straightforward and user-friendly semantics of
old_prog_fd (0 means "don't care") in few places.

36246d5a7a bpf: Tidy xdp attach selftests 
Support for cpumap and devmap entry progs in previous commits means the
test needs to be updated for the new semantics. Also take this
opportunity to convert it from CHECK macros to the new ASSERT macros.

Since xdp_cpumap_attach has no subtest, put the sole test inside the
test_xdp_cpumap_attach function.

d39aec79e5 selftest: Add tests for XDP programs in devmap entries 
Add tests to verify ability to add an XDP program to a
entry in a DEVMAP.

Add negative tests to show DEVMAP programs can not be
attached to devices as a normal XDP program, and accesses
to egress_ifindex require BPF_XDP_DEVMAP attach type.
