applaunchd: update and install agl-app@ template and sandboxing configs

The new applaunchd adds systemd_manager that allows launching apps as systemd
services in a sandboxed environment. And dbus_activation_manager is deprecated.

* Update SRCREV for the new code
* Bump version to indicate a major change
* Install supporting config files
* Add build dependency on systemd
* Add runtime dependency on polkit rule to manage agl-app@ services
