scripts/kernel-test: adjust to usr-merge

In debian bookworm, the /usr merge has been implemented:

  /bin → /usr/bin
  /sbin → /usr/sbin
  /lib → /usr/lib
  /lib64 → /usr/lib64

The initramfs filesystem layout is derived from the paths of the
binaries and libraries in the full system. Create the same symlinks and
adjust initrd_add_bin so it does not trip over the symlinks.

I've also considered to change all input for initrd_add_bin to point at
the /usr/… paths. But this is not possible, for example ldd/lddtree will
point at libraries in /lib and /lib64, and this gets passed to
initrd_add_bin.

Without this patch, the init script and all binaries called from it
cannot be executed.

scripts/kernel-test/run-qemu: set init=/init

Set init= so the kernel doesn't try to run other scripts if /init
fails:

[    2.946381] Run /init as init process
[    2.948885] Failed to execute /init (error -2)
[    2.949051] Run /sbin/init as init process
[    2.949329] Run /etc/init as init process
[    2.949566] Run /bin/init as init process
[    2.949795] Run /bin/sh as init process
