ostree-initrd: Make it an initramfs, not initrd
The reasoning here is to allow initramfs generated by this recipe
to be included in FIT.
To do so w/o changing openembedded-core (it allows only cpio format) -
init script should be able to execute from a rootfs (i.e. true initramfs),
not ramdisk (initrd).
See [1] for more information on these keywords.
The gist of this change is switch from `pivot_root` to `switch_root`.
This also allows to get rid of some clutter, since `switch_root` handles
transition to new sysroot all by itself.
Again, see [1] for details on these utility/syscall.
