Consider using solc-js and not a copy called solcWrap

[axic]

This piece of code seems to be an extract from solc-js:
https://github.com/trufflesuite/truffle/blob/next/packages/truffle-compile/solcWrap.js

Based on the change history, it seems it was introduced to speed up the load time: 729996d

The real solution would be to use require('solc/wrapper') which accomplishes the same.

The main reason the current approach is broken: 0.5.0 introduced a lot of changes, all of which are hidden by solc-js. If you update to solc-js 0.5.0, then it will work, but with the current wrapper, any new release won't be supported by truffle.
