ci: ensure saucelabs test output is human readable (#34277)

Currently the Saucelabs test output (also an issue in the POC bazel
saucelabs master-only cronjob), is very verbose because two Karma
reporters conflict. Basically resulting in the progress messages
being printed in new lines (while they usually are just updated
using a tty cursor reset).
