    ostbuild: Fix DB saving with /tmp and builddir in different volumes
    
    This fixes the case where /tmp resides in one volume, and the build
    directory in a different one: by storing the temporary file in the
    same directory as the target one, we avoid the case in which os.rename()
    would cross file system boundaries.
