    buildstats: check IMAGE_ROOTFS exists before checking its size
    
    After 0d6b7276003f1afabc6de683f663540327d52bdc, the exceptions are
    correctly checked if the rootfs size check fails. In case of a
    failure a build error is triggered.
    
    However, there are cases where this is known to fail (e.g.,
    with meta-swupd the rootfs for swupd images is other than IMAGE_ROOTFS).
    
    Because of that, check IMAGE_ROOTFS exists before trying to get the
    size of it. Also, in case of any error catched as err, simply print
    out a warning.
