Fix a few test cases to allow non-NULL map/packet/stack pointer with size = 0. Change a few tests using bpf_probe_read to use bpf_probe_write_user so ARG_CONST_SIZE arg can still be properly tested. One existing test case already covers size = 0 with non-NULL packet pointer, so add additional tests so all cases of size = 0 and 0 <= size <= legal_upper_bound with non-NULL map/packet/stack pointer are covered.
