common/Timer.h: ~SafeTimer needs to be virtual

Browse Source 
Fix for:

CID 1396232 ( of 1): Non-virtual destructor (VIRTUAL_DTOR)
 nonvirtual_dtor: Class librbd::<unnamed>::SafeTimerSingleton has a
 destructor and a pointer to it is upcast to class SafeTimer which
 doesn't have a virtual destructor.
