    Remove deprecated USE_GNOME2_MACROS from autogen.sh
    
    Use of USE_GNOME2_MACROS is deprecated in GNOME 3 and produced this
    warning:
    
        $ ./autogen.sh
        /usr/bin/gnome-autogen.sh
        ...
        ***Warning*** USE_GNOME2_MACROS is deprecated, you may remove it from autogen.sh
        ...
    
    It's use appears to have been removed first from GNOME 2.8 with this
    commit from 2004:
    
        https://git.gnome.org/browse/gnome-common/commit/?id=ea9e85851445efa0135c3f8d08c3d1ea53760d91
        delete some files that were unused after the reorganisation
    
    The oldest supported distribution is RHEL / CentOS 6 which is using
    gnome-common-2.28.0 from 2009.  Therefore unconditionally remove the
    USE_GNOME2_MACROS setting.
    
    Also confirmed that it makes no difference by running ./autogen.sh with
    and without USE_GNOME2_MACROS being set.  The produced GParted build
    trees were the same.  Therefore the release and executable can't be
    affected.
