Subject: [RFC PATCH bpf-next v1 11/11] selftests/bpf: Choose another percpu variable in bpf for btf_dump test

bpf_cgrp_storage_busy has been removed. Use bpf_bprintf_nest_level
instead. This percpu variable is also in the bpf subsystem so that
if it is removed in the future, BPF-CI will catch this type of CI-
breaking change.
