greylag: Silence boot logs

Boot prints out lots of text (e.g. graphics card warnings), all of which
is pointless to me or at the very least non-actionable. I also feel that
NixOS's rollbacking is good enough for me to be confident in disabling
boot logs for greylag.

I have not done so on a chimera level, as I feel that it's a personal
preference which you need to be quite aware of the risks to do. I feel
comfortable disabling logs on greylag but that doesn't mean that I have
them disabled on canvasback or that I am endorsing you to do the same.
