[OE-core] [PATCH 4/4] kernel-yocto: propagate in tree defconfigs to WORKDIR

[Bruce Ashfield]

As reported by Steffen Pankratz <Steffen.Pankratz at elektrobit.com>, the
previous logic of KBUILD_DEFCONFIG processing would not propagate an in
tree defcofig to WORKDIR if one was not already present.

We fix the propagation by copying the in tee config if a defconfig is
not already in WORKDIR.

Additionally we only warn (versus copying) if an in tree configuration
is specified, is different than the WORKDIR version and isn't copied.
