Add variants of perf_env__insert_bpf_prog_info(), perf_env__insert_btf()
and perf_env__find_btf prefixed with __ to indicate the
env->bpf_progs.lock is assumed held.
Call these variants when the lock is held to avoid recursively taking it
and potentially having a thread deadlock with itself.
Fixes: f8dfeae009 ("perf bpf: Show more BPF program info in print_bpf_prog_info()")
