selftests/bpf: Add some negative tests

Add a few negative tests for common mistakes with using percpu kptr
including:
- store to percpu kptr.
- type mistach in bpf_kptr_xchg arguments.
- sleep

selftests/bpf: Add some negative tests

Add a few negative tests for common mistakes with using percpu kptr
including:
- store to percpu kptr.
- type mistach in bpf_kptr_xchg arguments.
- sleepable prog with untrusted arg for bpf_this_cpu_ptr().
- bpf_percpu_obj_new && bpf_obj_drop, and bpf_obj_new && bpf_percpu_obj_drop
- struct with ptr for bpf_percpu_obj_new
- struct with special field (e.g., bpf_spin_lock) for bpf_percpu_obj_new
