selftests/bpf: Fix unused attribute usage in subprogs_unused test

Correct attribute name is "unused". maybe_unused is a C++17 addition.
This patch fixes compilation warning during selftests compilation.

Fixes: 197afc6314 ("libbpf: Don't attempt to load unused subprog as an entry-point BPF program")
