setup-dchroot: fix root directory permissions

When using stretch, the debootstrap process does not change the
permissions of the root directory of the chroot. As it is created
with mktemp, it ends up not being readable by a normal user like
"buildd". Change the permissions just before creating the tarball
to avoid that.
