vcontainer: add tiny initramfs image infrastructure
Add proper Yocto image recipes for the tiny initramfs used by
vdkr/vpdmn in the switch_root boot flow:
- vcontainer-tiny-initramfs-image.inc: Shared image configuration
- vcontainer-preinit_1.0.bb: Preinit script package (shared)
- vdkr-tiny-initramfs-image.bb: Tiny initramfs for vdkr
- vpdmn-tiny-initramfs-image.bb: Tiny initramfs for vpdmn
The tiny initramfs contains only busybox and a preinit script that:
1. Mounts devtmpfs, proc, sysfs
2. Mounts the squashfs rootfs.img from /dev/vda
3. Creates tmpfs overlay for writes
4. Performs switch_root to the real rootfs
This replaces ad-hoc file extraction with proper image-based builds,
improving reproducibility and maintainability.
