This change moves the hdkeychain package outside of the dcrutil directory into its own top-level package. This change is being made since hdkeychain only depends on dcrutil's address code, and if the rpctest integration tests are ever moved outside of the dcrd repo, hdkeychain will no longer be required to remain in dcrd to avoid a cyclic dependency.
