yetus: Remove calls to rand.Seed()

Fixes: golangcilint: 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. Programs that call Seed
with a known value to get a specific sequence of results should use
New(NewSource(seed)) to obtain a local random generator. (staticcheck)
