Daniel Borkmann 2b918fe2f1 selftests/bpf: Add tests for fault prone loads out of RCU pointers

Cover the two loads which used to lose the BPF_PROBE_MEM rewrite, both reached
from an RCU read-side critical section. The purpose of this patch is to assert
load success in order to make sure to not trigger verifier_bug_if() on
bpf_may_fault_on_deref() due to forgotten rewrite of a probed pointer.
