* evm: don't return extcode for validators
Due to technical debt, validator information is stored in the code field
of the address. The code field can be accessed in Solidity for an
arbitrary address using `extcodesize`, `extcodehash`, and `extcodecopy`
or helper commands (such as `address.code.Length`). The presence of this
field is used by contract developers to (erroneously) deny smart
contract access to other smart contracts (and therefore, validators).
This PR fixes that oversight by returning the same values as other EOAs
for known validator addresses. Obviously, it needs a hard fork that will
be scheduled separately.
