Let's allow override MigrateStart.hide_stderr when QTEST_LOG=3D1 is specified, because that means the user wants to be verbose. Not very nice to introduce the first QTEST_LOG env access in migration-test= .c, however it should be handy. Without this patch, I was hacking error_report= () when debugging such errors. Let's make things easier.
