Subject: selftests: proc: mark vsyscall strings maybe-unused
Date: Wed, 20 Aug 2025 23:26:10 +0530

The str_vsyscall_* constants in proc-pid-vm.c triggers
-Wunused-const-variable warnings with gcc-13.32 and clang 18.1.

Define and apply __maybe_unused locally to suppress the warnings.  No
functional change

Fixes compiler warning:
warning: `str_vsyscall_*' defined but not used[-Wunused-const-variable]
