Subject: [PATCH] lomiri.libusermetrics: Add custom patch for launching systemd
 service

The UserMetrics service expects AppArmor to be available, and its database access breaks when that's not the case.
Details: https://gitlab.com/ubports/development/core/libusermetrics/-/issues/8

We need to set an envvar for it to work AppArmor-less, but that requires system config knowledge.
Solve this by telling the D-Bus service to look for & launch a systemd service, which we will later create in the Lomiri module.
