Disable warnings_as_errors

[efcasado]

This is a bit of a blocker when trying to use this fork in an Elixir project using Elixir 1.6 and Erlang/OTP 20.

Thanks, can I ask what you're using this for? The fifo-0.9.2 branch of my fork is no longer maintained.

What would be a better fix here is if we adapt the code so we can keep warnings_as_errors but fix the things that are warning.

I went for fifo-0.9.2 because it is the default branch in your repo. It seemed to be the most trustworthy source for the latest and greatest version of riak_core after Basho's goodbye. Any suggestions on which one should I use?

I agree that the shortest path is not always the best option. I'll look into providing a less lazy solution for this.
