Temporarily work around crashing on Windows due to %zu

The printf functions on Windows don't support the z length modifier,
which can shift field arguments, and causes an unconditional crash in
modules.c on start-up. For now, strip it on Windows and have vlc work
again, until a better solution is found and applied.
