Subject: [PATCH 2/2] Get the default hasher indirectly

`DefaultHasher` wasn't stable until 1.13, at which point all the other
hashers were deprecated, so it's not easy for us to name a hasher type
to use for testing.  However, `RandomState` has been stable since 1.7,
and it implements `BuildHasher` that has a `Hasher` associated type.
