selftests/bpf: Test pointer bpf_loop iteration count rejection
Add a verifier test that leaves the raw tracepoint context pointer in R1
when calling bpf_loop(). This is the smallest trigger for the incorrect
precision backtracking: it reuses an existing callback and needs no maps or
userspace setup.
Expect an ordinary scalar-type rejection. Without the verifier fix, the
test instead reaches precision backtracking and reports an internal
"backtracking misuse" error.
