Revert "revert changes to root-builder"

This reverts commit a740009.

The problem seems to be that we don't have access to the network when
are running libguest tools. For example:
> #11 351.4 time="2024-07-26T13:04:42Z" level=warning msg="stderr> ntpdig: lookup of pool.ntp.org failed, errno -3 = Temporary failure in name resolution\n"

I can reproduce this locally. The problem seems to be that passt, which
is used for networking, cannot create a user namespace inside docker.

libguestfs: command: run: passt
libguestfs: command: run: \ --one-off
libguestfs: command: run: \ --socket /tmp/libguestfsPYvwlq/passt.sock
libguestfs: command: run: \ --pid /tmp/libguestfsPYvwlq/passt1.pid
libguestfs: command: run: \ --address 169.254.2.15
libguestfs: command: run: \ --netmask 16
libguestfs: command: run: \ --mac-addr 52:56:00:00:00:02
libguestfs: command: run: \ --gateway 169.254.2.2

Don't run as root. Changing to nobody...

No routable interface for IPv6: IPv6 is disabled

Couldn't create user namespace: Operation not permitted

The previous patch, however, AFAIU configures buildkit to run on the
host. Let's see if it works...
