systemd-systemctl: add handling of template unit files
Template unit files (those with '@' in their names) are not handled with
native version of systemctl. This is usually not a problem, as the
native systemctl fails and systemctl command is executed during first
boot. But some early boot template units may fail during first boot
because opkg configure for first boot is pulled too late for them
(although I encouter it only with some of my services, not with oe-core
ones).
Handling of template unit files is same as in original systemctl. Also
DefaultInstance directive in template is respected. As with original
systemctl, enabling of template without instance and DefaultInstance
does nothing.
