Valgrind: Remove starting() signal

It's only used internally as one-time communication between
worker and the *Tool singleton that handles toolbar button
states.

We basically start immediately after creation of the worker, so
any pre-start tool bar specific operations can be done at
RunWorker creation time.

Medium term, the runworker should proably steer "their" buttons
more directly.
