systemd: allow dots in arguments to template units
When installing systemd template units with an argument, the current code
removes characters between the '@' and the '.' from service names in
SYSTEMD_SERVICE_${PN}, e.g.:
getty@tty1.service -> getty@.service
This fails for services with dots in the argument (which is perfectly
legal in systemd), since the code searches only until the first dot.
E.g.:
vlan@eth0.1.service -> vlan@1.service
This is obviously wrong, and fails in systemd_populate_packages(), where
it fails to find the unit file.
Fix this by reworking the removal of the argument part of the service
name, so that parts before '@' and after teh last '.' are used as base
name.
