Support template units
Fix
deb-systemd-helper enable foo@1.service
will not work even if the
corresponding foo@.service is correctly in place.
Closes: #801822
This changes the behaviour how template units are treated to be:
Use foo@1.service as symlink name in /var/lib/systemd/deb-systemd-helper-enabled/x.target.wants/
Use foo@1.service.dsh-also as filename in in /var/lib/systemd/deb-systemd-helper-enabled/
The content of the dsh-also file shall be: /etc/systemd/system/x.target.wants/foo@1.service
And /etc/systemd/system/x.target.wants/foo@1.service shall be a symlink to /lib/systemd/system/foo@.service
