Remove workaround for old mkinitramfs-kpkg

* Makefile (install-client-nokey): Do not install
  "initramfs-tools-hook-conf".
* debian/control (mandos-client/Depends): Add "(>= 0.99)" to
  dependency on "initramfs-tools", since that is the version which
  removed mkinitramfs-kpkg.
* debian/mandos-client.dirs: Remove
  "usr/share/initramfs-tools/conf-hooks.d".
* initramfs-tools-hook-conf: Removed.

        If a client is compromised, its downtime should be duly noted
517
 
        by the server which would therefore declare the client
518
 
        invalid.  But if the server was ever restarted, it would
519
 
        re-read its client list from its configuration file and again
520
 
        regard all clients therein as valid, and hence eligible to
521
 
        receive their passwords.  Therefore, be careful when
522
 
        restarting servers if it is suspected that a client has, in
523
 
        fact, been compromised by parties who may now be running a
524
 
        fake Mandos client with the keys from the non-encrypted
525

526
 
        that case (if restarting the server program really is
527
 
        necessary) is to stop the server program, edit the
