Objdir entries in `OBJDIR_FILES` and `FINAL_TARGET_FILES` were installed with
`nsinstall`, which forces a fixed mode and installs only by basename, so it
drops the executable bit and cannot rename. Add a
`(source, target_basename)` tuple form to the `*_FILES` lists and install
those entries with a new `install_objdir_file` action that copies the file
preserving its mode, renaming to `target_basename`. Generated headers
under `dist/include` are the exception and keep the `nsinstall` bulk export,
where a fixed mode is fine.
This is the same rename that `RenamedSourcePath` already performed
internally for jar manifests, now expressible from `moz.build` and
supported by the RecursiveMake backend.
