    build: add GNU install to prerequisites
    
    The recent removal of usbutils from core and replacement by hwdata in
    packages has exposed hwdata's requirement for certain GNU options on
    'install' (-T)  Other packages (sqm-scripts) have openwrt specific
    makefile sections to avoid GNU options but I suspect this is going to
    get harder in the future.
    
    Add GNU install as a prerequisite and link into
    $STAGING_DIR/host/etc/bin as per similar GNU utils
    
    This resolves an issue building under MacOS which would otherwise use a
    non-GNU options aware version of 'install'
