integration-cli: seed rand in makeRandomString

Current uses of `makeRandomString` is to create really
long strings. In #10794, I used them to create nearly-unique
unix paths for the daemon. Although collions are harmless and
don't fail the tests, this prevents the same strings from being
created consistently in every run by seeding rand.Random.
