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.
