au_test_harness: Rename whitelist_chrome_crashes

Per go/COIL, we are renaming the test_that command-line arg
'whitelist-chrome-crashes' to 'allow-chrome-crashes'.
This CL changes the au_test_harness scripts to accommodate that change.

Uploaded with --no-verify because the lint errors were nontrivial to
fix.
