MT#61570 Do not install obsolete haveged

Quoting from <https://github.com/jirka-h/haveged/blob/master/README.md>:

  Starting from Linux kernel v5.4, the HAVEGED inspired algorithm has
  been included in the Linux kernel (see the LKML article and the Linux
  Kernel commit). Additionally, since v5.6, as soon as the CRNG (the
  Linux cryptographic-strength random number generator) gets ready,
  /dev/random does not block on reads anymore (see this commit).

Given that even Debian oldstable AKA bullseye is already at Linux 5.10,
we do not really need this daemon any longer.
