    populate_sdk_ext: explicitly set DL_DIR
    
    The eSDK generation assumes that DL_DIR is downloads/ under the build directory,
    and puts files such as a freshly buily uninative tarball in there expecting
    bitbake will find it later.
    
    Whilst ${TOPDIR}/downloads/ is in fact the default value for DL_DIR in
    bitbake.conf, and any instances of DL_DIR are removed from the original
    local.conf, there is still the possibility that other layers could contain a
    site.conf that assigns DL_DIR.
    
    If this happens the errors are quite mysterious as it fails to find the
    uninative tarball and so the hashes all change, and eSDK building fails.
    
    Ensure that this cannot happen by explicitly assigning the DL_DIR that we
    require, instead of assuming that the default value will be used.
