Adapt to changes in cryptsetup; use "cryptroot-unlock" program

* Makefile (install-client-nokey): Also install new script files
  "mandos-to-cryptroot-unlock" and "initramfs-tools-script-stop".
* debian/mandos-client.dirs: Add
  "usr/share/initramfs-tools/scripts/local-premount".
* initramfs-tools-hook: Also copy "mandos-to-cryptroot-unlock".
* initramfs-tools-script: Only modify keyscript setting in cryptroot
  file if the file exists, otherwise start
  "mandos-to-cryptroot-unlock" in background.
* initramfs-tools-script-stop: New script to make sure plugin-runner
  has stopped before continuing.
* mandos-to-cryptroot-unlock: New script to run plugin-runner and feed
  any password it gets into the "cryptroot-unlock" program.
