Subject: [PATCH bpf-next v6 13/13] selftests/bpf: Fix test_verifier failed test in unprivileged mode

Loading the BTF won't be permitted without privileges, hence only test
for privileged mode by setting the prog type. This makes the
test_verifier show 0 failures when unprivileged BPF is enabled.

Fixes: 4118e9e9def ("selftest/bpf: Test for use-after-free bug fix in inline_bpf_loop")
