bpf, selftests: Update test case for atomic cmpxchg on r0 with pointer

Browse source

commit e523102cb7 upstream.

Fix up unprivileged test case results for 'Dest pointer in r0' verifier tests
given they now need to reject R0 containing a pointer value, and add a couple
of new related ones with 32bit cmpxchg as well.
