bootstrap: die if init binary could not get diverted

Browse Source 
This is a safe guard check, as otherwise DAB might end up putting the
wrong 'init' executable in the final image, like it happened for
Ubuntu 24.04 before the fixing commit d2e70cf ("explicitly add
systemd-syv to required packages for systemd based releases").
