[PATCH 06/16] dyndbg: fix overcounting of ram used by dyndbg

[Jim Cromie]

during dyndbg init, verbose logging prints its ram overhead.  But it
counted strlens of all ddebug callsite entries, which are full of
pointers into shared __dyndbg memory, and shouldnt be counted at all
(since theyre already in the __dyndbg section)
