Fix a build failure on OpenBSD 4.x and MirBSD.

* sysdep.c (list_system_processes): Make it a stub on all BSD_SYSTEM
hosts, except for DARWIN_OS and FreeBSD where it's been tested.

Fixes: debbugs:13881

        Fix a build failure on OpenBSD 4.x and MirBSD (Bug#13881).
-       * sysdep.c (list_system_processes) [__OpenBSD__ || __MirBSD__]:
+       * sysdep.c (list_system_processes)
+       [BSD_SYSTEM && !DARWIN_OS && !__FreeBSD__]:
        Make it a stub in this case; otherwise the build might fail,
-       and even if the build worked the function would just return nil anyway.
+       and this code hasn't been tested on such hosts anyway.
