home: vim: tree-sitter: use explicit buffer option

Because of DPMS, I would still get a screen-lock after a 10-minute
timeout.

I think the `xset s {on,off}` part is not _strictly_ necessary, but a
little bit of cargo-culting never hurt anybody.

According to the `xss-lock` man page `xset s on` use hard-coded values,
not my preferred timeouts. Given that I rely on `xautolock` anyway, I
don't care about the timeouts and set them to `0`.
