Gary Miguel 35f374036c Revert "Revert "Use runTests in fuchsia tester. (#19178)" (#19321)" (#19327)
This reverts commit e22f99743b4f0bea4a9b8e7703ce5ffbfda37a04.

Adding the exit(exitCode) fixes the hang.
Tested by running `fx run-host-tests` with a topaz checkout.
Verified the hang before, no hang after.
