fix build with tcmalloc on Freed-ora 13

[Alexandre Oliva <oliva@lsd.ic.unicamp.br>]

G++ complains about the difference between the return type of tcmalloc's
IsHeapProfilerRunning (int) and the return type of the function that
g_conf.profiler_running is supposed to point to (bool).  We could
probably get away with a type-cast, but as a compiler developer and
former C++ language lawyer, I'd rather not take the risk of destroying
the universe by invoking undefined behavior ;-)

The one thing I'm not sure about is whether the type of profiler_running
is always going to be bool.  If you know otherwise, let me know, and
I'll come up with some C++ template trickery to infer the appropriate
type.
