selftests/bpf: Add test for zero offset or non-zero offset pointers as KF_ACQUIRE kfuncs argument
This patch adds test cases for zero offset (implicit cast) or non-zero
offset pointer as KF_ACQUIRE kfuncs argument. Currently KF_ACQUIRE
kfuncs should support passing in pointers like &sk->sk_write_queue
(non-zero offset) or &sk->__sk_common (zero offset) and not be rejected
by the verifier.
