Instead of just copying the hosts mtab use findmnt. This way only reachable mount points are shown.

This will create chroots on demand if needed.

This makes it possible to use e.g. install=$pkgname.install

also set some sane default options

TEMPDIR is used before packages are copied into it and made it fail
because cannot find any.

* Set first enabled mirror found mirrorlist as mirror within the chroot.
* If the mirror is local bind its directory read-only into the chroot.
* Fallback is the kernel.org mirror.

Use en_US.UTF-8 and de_DE.UTF-8 by default (the latter is needed for some packages like gcc)
