[PATCH v6 6/6] migration-test: Only hide error if !QTEST_LOG |

The errors are very useful when debugging qtest failures, especially when
QTEST_LOG=1 is set. Let's allow override MigrateStart.hide_stderr when
QTEST_LOG=1 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.
