    devtool: sdk-update: drop support for local updates
    
    Having two code paths here makes maintenance difficult, and it doesn't
    seem likely that you would use the local case in real usage anyway, so
    drop the local support entirely.
    
    This should allow us to resolve [YOCTO #9301].
