[PATCH 3/5] kernel: Add kernel headers to kernel-dev package

[Darren Hart <dvhart@linux.intel.com>]

[YOCTO #1614]

Add the kernel headers to the kernel-dev package. This packages what was
already built and kept in sysroots for building modules with bitbake.
Making this available on the target requires removing some additional
host binaries.

Move the location to /usr/src/kernel

Before use on the target, the user will need to:

    # cd /usr/src/kernel
    # make scripts

This renders the kernel-misc recipe empty, so remove it.
