SystemRandomness

The real source of entropy: SystemRandomness::bytes()/SystemRandomness::int() answer from PHP’s CSPRNG exactly like random_bytes()/random_int() always did.

This is what the container binds RandomnessInterface to by default; nothing here is mockable, which is the point — tests reach for SeededRandomness instead of stubbing this class.
