ci/db410c: Fix networking so we get artifacts from our jobs.

Seems some sort of linux change (bugfix?) resulted in the db410cs
selecting device mode for the db410cs due to the micro cable being
plugged in (fastboot runs them in device mode), so we weren't finding
the network and getting artifacts out.

Closes: #3728
