Subject: [PATCH 6/8] systemctl,core: allow nuking of symlinks to removed units
Before, one the unit file was deleted, install_context_for_removal()
would refuse to look for symlinks. But we can remove dangling symlinks
anyway.
In principle, package installation/deinstallation scripts should do
that before the unit is uninstalled, but they don't always do. Also,
a user might have added additional symlinks manually.
