run_dev.sh: Enable tests to fail gracefully

[bsb808]

Issue

When following the issac_ros_nvblox quickstart tutorial the verification of host setup (e.g., checking to see if git-lfs is installed) fail silently. This is because of the set -e fail fast option which exits before the output to stdout.

Fix

I added edits to two of the obvious checks that will fail silently enabling them to provide the desired reporting to stdout.
