changegroup: progress for added files is not measured in "chunks"

The "prog" class cg1unpacker.apply() has the unit set to
"chunks". This is not correct for files, where the file itself is the
unit. The unit is not usually printed, which is probably why this has
not been fixed yet. It can be show with e.g. "--config
progress.format='topic number unit'".
