[PATCH 03/14] security/Kconfig.hardening: Remove tautological condition from FORTIFY_SOURCE

Now that the minimum supported version of LLVM for building the kernel
has been raised to 17.0.1, the '!X86_32 || !Clang || Clang > 16'
dependency of CONFIG_FORTIFY_SOURCE is always true, so it can be
removed.
