1. install: Re-implement hostns to work around supermin …

   I'm experimenting with doing `bootc install` in a supermin VM
   like we do in coreos-assembler, but hit upon the fact that supermin's
   `/sbin/init` implementation incorrectly does `chroot()` instead of
   a `pivot_root`:
   
   https://github.com/libguestfs/supermin/blob/5230e2c3cd07e82bd6431e871e239f7056bf25ad/init/init.c#L288
   
   The problem here then is doing `nsenter` just takes us into the
   original rootfs, and all the real content is in `/root`.
   
   Re-implement this by re-executing our own binary and doing the `setns()`
   and `chroot()` dance internally, because we can't really do it
   with external binaries.
