Function buildPackageTests

buildPackageTests groups failedTests by package into the wire format flakeapp expects. If fakeRepo is non-empty, tests with no real issue URL (i.e. not marked via flakytest.Mark) get a fake URL of the form https://github.com/{fakeRepo}/issues/UNKNOWN. If fakeRepo is empty, those tests are simply om
