PackageWriterImpl::_AddEntry(): Fix update logic

Browse Source 
* Don't only look up the entry attribute when the entry is implicit.
  Look it up, when it is a directory instead. This aligns it the logic
  with _UpdateCheckEntryCollisions().
* When the entry attribute exits and the entry is not implicit, add file
  attributes, but not stat data. This also aligns the logic with
  _UpdateCheckEntryCollisions(), which removes colliding attributes, but
  keeps stat data.
