Guard prof related mallctl with opt_prof.

Browse Source 
The prof initialization is done only when opt_prof is true.  This change makes
sure the prof_* mallctls only have limited read access (i.e. no access to prof
internals) when opt_prof is false.

In addition, initialize the global prof mutexes even if opt_prof is false.  This
makes sure the mutex stats are set properly.
