Anton Maklakov f3d61015f7 build: Fix problems with building kconfig and generating sdkconfig
We had some problems:
    simultaneous compiling of kconfig in the same tree;
    attempt to use menuconfig in some examples and ut in batch mode (w/o interactive console)

Also increase debug abilities in CI:
    force non-interactive building;
    add variable DEBUG_SHELL to toggle verbosity of scripts
