NOTE: This will be a shared mount, due to root being turned into a
shared with `MC_REC` set: `mount("", "/", "", rec|shared, "")`.
For some reason setting `shared` when mounting `/sys/fs/bpf` doesn't
work at all, perhaps that's just a kernel feature.

Use unix.Reboot from golang.org/x/sys/unix for poweroff and reboot
instead of relying on external commands.

This removes more shell scripts to improve maintainability.
This now also works correctly in userspace, so it can be used for
running LinuxKit images in Docker and other such use cases.
It is a literal conversion of the shell scripts with a few small
tweaks.
