Linux/macOS: explicitely initialize hash algo before hashing random pool

Browse Source 
The lack of explicit hash initialization was causing issue with Blake2s
because it doesn't allow further processing once a digest value was
returned.
Other hash algorithms don't have this restriction.
Not we explicitely initialize all hash algorithms which is the correct
way to do things.
