barebox.bbclass: set KBUILD_OUTPUT

Sets KBUILD_OUTPUT to the build directory to ensure using the valid
path in e.g. menuconfig or devshell.

An externally set KBUILD_OUTPUT could otherwise confuse the build
process and create the .config from an invalid folder.

This is what the kernel recipes also do.
