root: silence staticcheck note about deprecated rand.Seed

The latest lint CI run failed with

  SA1019: rand.Seed has been deprecated since Go 1.20 and an
  alternative has been available since Go 1.0: As of Go 1.20 there is
  no reason to call Seed with a random value. [...]

So once our minimum Go version is 1.2.0, we can remove this.
