[OE-core] [RFC][PATCH] kernel: Enable externalsrc on kernels which instantiate kernel.bbclass

This also make a change where for kernel
S != B, this is done because when S = B
and we use O= option or set KBUILD_OUTPUT
to point to objectdir, kernel build system
ends up denoting itself dirty and asking for
running mrproper during later build steps
after do_configure but works perfectly
for when S != B
Additional fixes make sure that we do not
assume directory paths when accessing files
Move exporting KBUILD_OUTPUT from kernel-yocto
into kernel class
