synthrepo: new filenames must not also be new directories, and vice-versa
When generating many new files into a set of many possible new directories,
there is the possibility that the same path is chosen as both file and
directory. How likely this is depends on the size of the dictionary used,
the generated directory structure and the number of generated files.
status: don't override _buildstatus() in workingcommitctx
Now that the caching into _status is done in
workingctx._dirstatestatus(), which workingcommitctx._dirstatestatus()
does not call, there is no caching to prevent in _buildstatus(), so
stop overriding it.
