bitbake: fetch2: Skip lockfiles and donestamps for local files

For local files, there are no races with downloads, we don't need ".done"
stamps and we don't need lockfiles.

This considerably cleans up DL_DIR and all the pointless ".done" files
as well as removes stalls over local files with the same name.
