Fix api-v2 branch build (#2825)

## Problem

The `api-v2` branch does not build in OBS. There are two problems:

1. Agama crashes if the l10n monitor cannot connect to the systemd
locale service, which is not available when running the tests in OBS.
1. The `agama-services` is not part of the Rust package anymore.

## Solution

The solution for the 2nd point is trivial. About the 1st one, we have
decided that Agama should not crash, just report (in the logs) that it
cannot observe system locale changes.
