status: don't list files as both clean and deleted

Tracked files that are deleted should always be reported as such, no
matter what their state was in earlier revisions. This is encoded in
in two conditions in the loop in basectx._buildstatus() for modified
and added files, but the check is missing for clean files. We should
check for clean files too, but instead of adding the check in a third
place, move it earlier and skip most of the loop body for deleted
files.
