GM self-tests: always run all tests (don't stop at first failure)

gm/tests/rebaseline.sh

 #!/bin/bash
 
 # Rebaseline the outputs/*/output-expected/ subdirectories used by the
 # gm self-tests.
 # Use with caution: are you sure the new results are actually correct?
 #
-# YOU MUST RE-RUN THIS UNTIL THE SELF-TESTS SUCCEED!
-# (It takes one run for each failing call to gm_test in run.sh)

 # TODO: currently, this must be run on Linux to generate baselines that match
 # the ones on the housekeeper bot (which runs on Linux... see
