[Bug 1659541] [NEW] name resolution fails in vmdebootstrap with setup-testbed customize script

[Jean-Baptiste Lallement]

Public bug reported:

On Ubuntu Zesty, I'm running the following command to provision a debian/sid VM:
sudo vmdebootstrap \
    --verbose --serial-console --distribution=sid \
    --customize=./setup-testbed --user=test/test \
    --size=8G --grub --image=$IMAGE \
    --sudo --convert-qcow2 \
    --log vmbootstrap.log --log-level debug

It fails on this command:
+ chroot /tmp/tmpno5Yk_ apt-get update
Err:1 http://httpredir.debian.org/debian sid InRelease
  Temporary failure resolving 'httpredir.debian.org'
Reading package lists... Done

Name resolution works fine on the host but does not inside the chroot.
In the chroot, /etc/resolv.conf is a link to /run/systemd/resolv.conf but the target does not exist (/run is not mounted) 
Name resolution works after mounting /run from the host inside the chroot.
