Adolfo Delorenzo 5cf81049f6 fix: install our staged init at /init too, not just /sbin/init ...

The kernel ALWAYS runs /init when booting from an initramfs. If /init doesn't
exist, the kernel falls back to the legacy root-mount path (looking for a real
root partition via root= cmdline), which we don't want — our system IS the
initramfs.

Previous fix removed piCore's /init to stop it from being run; that caused the
kernel to skip the initramfs entrypoint entirely and panic with 'Cannot open
root device' (error -6).

Correct fix: replace piCore's /init with a copy of our init.sh. The kernel
runs /init -> our staged boot, which is exactly what we want. Keep
/sbin/init as well (some boot paths exec it directly, e.g. via init= cmdline
override) and the existing init=/sbin/init in grub-arm64.cfg as a belt.
