Some more cleanup in the commit harvester status walker.

Suggested by: gstein

* subversion/libsvn_client/commit_util.c
  (harvest_not_present_for_copy): Use separate arguments instead of the walker
    baton.
  (harvest_status_callback): Remove variables for two unused status flags.
    Excluded and not-present nodes are reported as unversioned by the status
    walker. Update caller.
