Don't increment the trace TcmallocContentionCycles counter on OSX

Currently the OSX build is broken because of this call, on line 341
of spinlock_profiling.cc:
...
t->metrics()->IncrementTcmallocContentionCycles(wait_cycles);
...

Not sure what the cause is, but ifdef'ing it out on OSX fixes the problem.
