[Resource Encapsulation] removing "boost/atomic.hpp" from ResourcePressence.h

[Resource Encapsulation] removing "boost/atomic.hpp" from ResourcePressence.h

That was removed because Tizen 2.3 uses boost 1.51 which doesn't have "boost/atomic.hpp"
Instead of boost::atomic_long,  std::atomic_long has been applied and related module has been changed
 -  (receivedTime.load(boost::memory_order_consume) is changed to "receivedTime"
    at ResourcePresence::timeOutCB  from ResourcePressence.cpp
