include/debug: don't print pointer address for SUID programs

Browse source 
* introduce new flag __UL_DEBUG_FL_NOADDR to suppress pointer address printing

* use __UL_DEBUG_FL_NOADDR when SUID

* move ul_debugobj() to debugobj.h, and require UL_DEBUG_CURRENT_MASK
  to provide access to the current mask from ul_debugobj(). It's better
  than modify all ul_debugobj() calls and use the global mask as
  argument.

* remove never used UL_DEBUG_DEFINE_FLAG
