kernel-yocto: pass the build directory to configme

configme used to be able to calculate the output/build directory
when branches were always <machine>-<kernel type>. Branch names
can now be widely different and to avoid embedding complexity
in the scripts it is easier to just pass ${B} from the build system
down to the scripts.
