    scripts: mkits.sh: replace @ with - in nodes
    
    U-boot will reject the nodes with @ for the address since
    commit:
    https://gitlab.denx.de/u-boot/u-boot/-/commit/79af75f7776fc20b0d7eb6afe1e27c00fdb4b9b4
    
    This in turn will cause the failure to boot with OpenWrt
    generated images.
    
    So, to rectify that simply replace @ with -.
