[PATCH v2 0/2] selftests/bpf: convert test_xdp_veth to test_progs framework

Hello everyone,

this small series is a first step in a larger effort aiming to help improve
eBPF selftests and the testing coverage in CI. It focuses for now on
test_xdp_veth.sh, a small test which is not integrated yet in test_progs.
The series is mostly about a rewrite of test_xdp_veth.sh to make it able to
run under test_progs, relying on libbpf to manipulate bpf programs involved
in the test.

Changes in v2:
- fix many formatting issues raised by checkpatch
- use static namespaces instead of random ones
- use SYS_NOFAIL instead of snprintf() + system ()
- squashed the new test addition patch and the old test removal patch
- Link to v1: https://lore.kernel.org/r/20240711-convert_test_xdp_veth-v1-0-868accb0a727@bootlin.com
