systemd /etc/resolv.conf setup on new installation breaks in-target package installation.

This Ubuntu systemd commit breaks in-target package installation on netboot installs.

The netboot initrd does not use systemd. /etc/resolv.conf is an actual generated file and there is no /run/systemd/resolve/stub-resolv.conf.

Package installation in /target is done through in-target. in-target bind mounts the initrd /run to /target/run. After base-installer installs the systemd deb in /target, any subsequent in-target invocation to install a package fails. The repository containing the package cannot be resolved because /target/etc.resolv.conf will be a symlink to the bind mounted
non-existent /target/run/systemd/resolve/stub-resolv.conf from the initrd.
