meta: introduce ostree-kernel-initramfs recipe

We package kernel image, devicetrees, initramfs and install them to
/usr/lib/modules/${KERNEL_VERSION}, which is the preferred location
according to ostree's new implementation, this could simplify the
deployment.

Reference:
https://github.com/ostreedev/ostree/commit/3ab0d5e6644885440bac6abd17b6d2637df5435f

To let initramfs-ostree-image be able to be depended by
ostree-kernel-initramfs, it must inherit nopackages to avoid a annoying
QA warning like the follows:
| WARNING: initramfs-ostree-image-0.0.1-r0 do_package: Manifest ...initramfs-ostree-image.packagedata
| not found in colibri_imx6 armv7ahf-neon-imx armv7at2hf-neon-imx armv7at2hf-neon armv7ahf-neon armv7at2hf-vfp
| armv7ahf-vfp armv6thf-vfp armv6hf-vfp armv5tehf-vfp armv5ehf-vfp armv5thf-vfp armv5hf-vfp allarch
| x86_64_x86_64-nativesdk (variant '')?

Also we need define OSTREE_KERNEL, OSTREE_DEPLOY_DEVICETREE and
OSTREE_DEVICETREE in sota.bbclass so they could be accessed in other
recipes as well as in image recipes.
