selftests/bpf: Add test passing MAYBE_NULL reg to bpf_refcount_acquire
The test added in this patch exercises the logic fixed in the previous
patch in this series. Before the previous patch's changes,
bpf_refcount_acquire accepts MAYBE_NULL local kptrs; after the change
the verifier correctly rejects the such a call.
