Fix test errors

* Implement node::MakeCallback between 8.0.0 and 8.6.0 to fix
  unresolved symbol
* Fix error message expectation (was: "Invalid pointer", is: "Invalid
  argument")
* Add -fvisibility=hidden to the compilation of sources of node_api.a
  so as to avoid conflicts with Node.js symbols

Fixes: #142
Fixes: #282
