linux-yocto: move build / debug dependencies to .inc

When the architecture and debug specific build and runtime dependencies
were introduced, they were only applicable to "newer" kernel versions
and were enabled in the version specific recipes.

These are now common dependencies, so we can avoid the duplication and
move them to a common location.

We also change the adhoc nature of the existing elfutils definition,
as it is now detected by the kernel build and we no longer need the
work around to the native sysroot.

Finally, we change the undocumented KERNEL_DEBUG_OPTIONS to KERNEL_DEBUG
and use it to conditionally enable features that need extended support
(and support sometimes out of oe-core).

(From OE-Core rev: 7ddeb149e7a78bedeb945898fec5e8f13b7c5711)
