install: follow config_path symlink (#3362)

Under NixOS, the config_path /etc/systemd/system is a symlink to
/etc/static/systemd/system. Commands such as `systemctl list-unit-files`
and `systemctl is-enabled` did not work as the symlink was not followed.

This does not affect how symlinks are treated within the config_path
directory.
