The `repo` documentation says:
"If the url is missing and the path defined, this entry references the
directory the path points to. [...] In case of a relative path name
`kas_work_dir` is prepended."
But if no `url` is given and a relative path is given in `path`, then
the layer paths being added to `bblayer.conf` are missing the
`kas_work_dir` prefix.
This patch fixes it.
