Subject: [PATCH] nixos/tests/dawarich: fix points being flagged as anomalies

Due to a change upstream [1], points with velocity over 1000 km/h are
flagged as anomalies and do not show up in the /points endpoint.
This results in an assertion failure.

To fix this, the dummy data file that was in use has been replaced with
custom data that has spaced out timestamps, which avoids the points
being flagged as anomalies.
