kernel: Fix non linux-yocto builds

After the recent kernel changes, non linux-yocto builds stopped working
properly for two reasons:

a) ${S} was being reset to ${WORKDIR}/git for example and STAGING_KERNEL_DIR
   did not contain the source

b) Most builds were using ${B} == ${S}

This patch adds a fixup to the unpack function to handle the case where
${S} != ${STAGING_KERNEL_DIR} and also set up the infrastrcture so that
B != S for kernel builds from now on. The kernel build system is one of the
best for supporting this and there is no good reason not to take advantage
of it.
