image: call systemctl preset-all for images

Rather than rely on systemd's default invocation of preset-all at
runtime, we pre-populate the symlink tree as part of of the image. This
is done late so any overrides of presets during rootfs construction
should already have happened.

Whilst we don't strictly need this for the read-write root case, it
avoids boot time churn; for read-only root we have to do it here.
