selftests/bpf: Fix check_mtu using wrong variable type Dan Carpenter found via Smatch static checker, that unsigned 'mtu_lo' is never less than zero. Variable mtu_lo should have been an 'int', because read_mtu_device_lo() uses minus as error indications.

selftests/bpf: Migrate from bpf_prog_test_run_xattr bpf_prog_test_run_xattr is being deprecated in favor of the OPTS-based bpf_prog_test_run_opts. We end up unable to use CHECK_ATTR so replace usages with ASSERT_* calls. Also, prog_run_xattr is now prog_run_opts.

selftests/bpf: Turn on libbpf 1.0 mode and fix all IS_ERR checks Turn ony libbpf 1.0 mode. Fix all the explicit IS_ERR checks that now will be broken because libbpf returns NULL on error (and sets errno). Fix ASSERT_OK_PTR and ASSERT_ERR_PTR to work for both old mode and new modes and use them throughout selftests. This is trivial to do by using libbpf_get_error() API that all libbpf users are supposed to use, instead of IS_ERR checks. A bunch of checks also did explicit -1 comparison for various fd-returning APIs. Such checks are replaced with >= 0 or < 0 cases. There were also few misuses of bpf_object__find_map_by_name() in test_maps. Those are fixed in this patch as well.
