Add LazyInstanceTest.PriorityInversionAtInitializationResolves

This test ensures that LazyInstance initialization isn't blocked
by priority inversions when mixed-priority threads try to
initialize the same LazyInstance object. That is, test to make
sure r527445 works.

On my Z840, this test takes 5 to 10 seconds to complete without
r527445 but ~30ms with it :). An explicit 5s timeout was added to
this test to make the regression case indeed fail (instead of
relying on the longer test timeout under which it's mostly fine).
