dyndbg: cleanup auto vars in dynamic_debug_init

Browse source 
rework var-names for clarity, regularity
rename variables
  - n to mod_sites - it counts sites-per-module
  - entries to i - display only
  - iter_start to iter_mod_start - marks start of each module's subrange
  - modct to mod_ct - stylistic

new iterator var:
  - site - cursor parallel to iter
    1st step towards 'demotion' of iter->site, for removal later

treat vars as iters:
  - drop init at top
    init just above for-loop, in a textual block
