Don't install the cryptsetup initramfs integration and startup scripts (Closes: #16264)
We probably only need the binaries. Not installing the initramfs integration will get rid of this noise: update-initramfs: Generating /boot/initrd.img-4.19.0-1-amd64 cryptsetup: WARNING: Couldn't determine root device cryptsetup: WARNING: The initramfs image may not contain cryptsetup binaries nor crypto modules. If that's on purpose, you may want to uninstall the 'cryptsetup-initramfs' package in order to disable the cryptsetup initramfs integration and avoid this warning.
