testlib: Defer signal dumper start until tests are ready to run

We don't want the signal dumper to pick up signals that our own
test machinery produces, such as the ones emitted from the watchdog
thread startup and shutdown. This would otherwise produce:

 tst_Signaldumper::initTestCase() Signal: QThread(7fc969e0d870) started ()

At startup, and at shutdown even more confusingly:

 tst_Signaldumper::UnknownTestFunc() Signal: QThread(7fc969e0d870) finished ()
