Wait until target has domain name resolution

If apt-get -y runs before the target has finished initializing its
network it's going to fail to fetch some packages, but will report
success anyway. Run resolvectl query in a loop until it can resolve
deb.debian.org to reduce the likelihood of generating an image with
missing packages.
