selftests/bpf: Add a kernel flag test for LSM bpf hook

2025-03-15T18:48:58+00:00

This test exercises the kernel flag added to security_bpf by effectively blocking light-skeletons from loading while allowing normal skeletons to function as-is. Since this should work with any arbitrary BPF program, an existing program from LSKELS_EXTRA was used as a test payload.
