There is currently a problem where the rootfs in an initramfs image for
single target build is not updated on subsequent run. This is caused by
a bug introduced in d78dec3e19e3 ("kernel: copy kernel build dir on
Per-Device Initramfs compilation") where the initramfs_data.cpio rm was
moved to PrepareConfigPerRootfs. This caused the side effect of dropping
the rm call for single target build making the kernel reusing the
previous generated initramfs_data.cpio.

To correctly handle this, restore the original location of this call
right after the touch /init call. This way the kernel will always
regenerate the initramfs embedded rootfs ALSO for single target build.

Fixes: d78dec3e19e3 ("kernel: copy kernel build dir on Per-Device Initramfs compilation")
