The rest of utils.cc does not depend on art::Runtime. This separates
the part dependent on that class, so that including utils.cc in the
build does not require the entire Runtime. Another preparatory cleanup
to getting tools to build on Windows.

We were letting the jit and the main thread race on class definition.
If the 'leader' changes then we would end up with the test class

this by making sure all threads get the same definition regardless of
speed.
