build system: fix another cbfstool race

It just doesn't work to have files depend on their parent
    directory: As soon as the files are written, the time stamp
    of the directory changes, too.

This led to spurious updates of cbfstool and rmodtool, and
    related "permission denied" errors when linker and build
    system ran into each other.
