RFR: 8308969: make test-prebuilt doesn't return the correct exit code [v3]

[Antonios Printezis]

> For 'make' test and 'make test-only' the existence of exit-with-error is checked in the main target in Init.gmk. Is there a better way to fix this than to check for the existence of exit-with-error in RunTestsPrebuilt.gmk?
