Revert^2 "Ensure that run-test preserves exit status"

We failed to update the run script for test 134 which would exit
non-zero in cases where dex2oat is disabled. This caused the test to
fail in some configurations.

This reverts commit d8c88c71.

Reason for revert: Fixed issue with test 134
Test: ./test/testrunner/testrunner.py --host -t 134-nodex2oat-nofallback --no-prebuild --no-relocate
