kernel-yocto: ensure that only a single defconfig is processed

As a follow up to the changes to ensure that KBUILD_DEFCONFIG will
always get its defconfig into the processing, we also should ensure that
we don't get both a KBUILD_DEFCONFIG and a SRC_URI defconfig in the
configuration queue. If both are in the configuration queue, we end up
with competing values and a potentially long running check of 5000+
options x 2 against the final .config.

By removing the defconfig found from the SRC_URI when one is found
via KBUILD_DEFCONFIG, we ensure that only one will be processed.
