Remove the check_uptodate conf checks

We recently removed the checkupdate tests for sample.conf
here Ie4e25a8cd36782007a8934cc4573632f5215c2b1

To stop gating on this as it's just a big fat
pain when external libs change.

Instead, we'll start generating this in an external
job and publishing somewhere.

Funny thing though, we actually have a direct call in
run_tests.sh as well.

This patch removes the second call in run_tests.sh
