Simplify Trie Dependencies (#4259)

Make the ethereum/trie and services/kvstore modules  as slim as possible
by dropping dependencies.

* The ':util' api dependency is removed from kvstore  and added to
   eth module
* Move tries's kvstore dependency to test
* Other dependencies are removed as unused from trie and kvstore
