Paravirtualization Support #1834

From what I can tell, it seems like the Brunch kernels are being built without paravirtualization support (CONFIG_PARAVIRT and VirtIO drivers.) This could be bad for performance inside Crostini and the new arcvm.

Ok small question @peter-marshall5 have you tried this? I haven't seen any abnormal performance regressions in Crostini (within Brunch) as compared with native Linux but I'll try building a build with those changes on my CI repo and see later.

I've tried it, but I haven't actually benchmarked anything properly yet. All I can say for now is that it doesn't introduce any new issues.

My desktop decided that it didn't want to build...
