Subject: selftests/bpf: Fix unused attribute usage in subprogs_unused test
Patch-mainline: v5.10-rc5
Git-commit: fd63729cc0a6872bdabd393ee933a969642e4076
References: bsc#1177028

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

Fixes: 197afc631413 ("libbpf: Don't attempt to load unused subprog as an entry-point BPF program")
