lib/ascii: replace package "math/rand" with "crypto/rand"

Since Go 1.20 the "math/rand.Seed" is considered deprecated (the initial
value of rand is seeded automatically, not zero).

Now, it is the time to replace "math/rand" with more secure random number
generator, from "crypto/rand".

This changes affect tests in package "lib/email", "lib/http", and
"lib/stmp".
