Fix clear-config in build-all-clusters-app.py

[cecille]

Problem

clear-config argument stopped working when we swapped over to the new way of building.

Change overview

Fixes the script so you can run with --clear-config and it will bring up the menuconfig with the proper default.

Testing

• ran script with --clear-config and various arguments.

I don't understand this line. I'd expect == here, not !=. If there is something deep here that I am missing about what "curr" means, it should at least be documented.

[cecille]

This is just because the variable is strangely named - "clear_config" basically just re-runs menuconfig starting from the given default. If the default is "curr" (ie, re-run menuconfig, but starting from the current configuration), then we don't need to delete the current configuration and replace the default.

I tried to keep the name because I thought it would be less confusing, but given that this script has been broken for a while now, it would appear I'm likely either the only one or one of the only ones using this. If I renamed this something like menuconfig_with_default, would that work? it would change how the script gets invoked, but I'm not sure it'll actually affect anyone.

I think fixing the naming would be helpful, yes! I'm fine with a followup for that.
