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. https://bugs.freedesktop.org/show_bug.cgi?id=62395
