    ath79: remove duplicate sysupgrade.bin for dlink_dap-2xxx
    
    sysupgrade.bin has been added to IMAGES twice, resulting in
    warnings like:
    
    Makefile:86: warning: overriding recipe for target
      '[...]/tmp/openwrt-ath79-generic-dlink_dap-2660-a1-squashfs-sysupgrade.bin'
    Makefile:86: warning: ignoring old recipe for target
      '[...]/tmp/openwrt-ath79-generic-dlink_dap-2660-a1-squashfs-sysupgrade.bin'
