[ethcore]: reduce re-exports (#11059)

* [ethcore]: reduce re-exports

Last piece of refactoring to close #10130 after work done by @dvdplm et. al

After this PR, we have the following re-exports from other crates in `non-testbuilds`:
- evm::VMType (client)
- ethcore_miner::local_accounts::LocalAccounts (miner)
- ethcore_miner::pool::PendingOrdering (miner)

I think the miner re-exports make sense (closely tied to the module) and `VMType` (related to module but not closely)

* fix(grumbles): remove re-export `VerifierType`
