Added libresolv to the whitelisted libraries

Fix #80

[njsmith]

Ugh, it looks like the Travis tests have bitrotted. @rmcgibbo @ehashman any ideas?

[ehashman]

Hmmmm, at first glance I don't think this is bitrotted. If we add a new file to the policy we'll need to also ensure all its symbols are represented in the policy list. Perhaps that's why this failed?

[njsmith]

The library's part of glibc so it shouldn't need any new symbols.

From a quick glance it looked like the tests were failing because they were trying to fetch some remote url and getting a 404.

looks at Travis build

Aha, I dunno what https://github.com/getnikola/wheelhouse/archive/v2.7.zip is but it's 404ing. That definitely isn't a test I wrote. Will let y'all take a look first.

Is anyone working on fixing these build problems? They seem unrelated to this pull request. This issue affects other libraries that we are building our own wheels for; for example mysqlclient.

[rmcgibbo]

I don't think anyone is working on fixing the build problems. It's my code / my fault. The 404 is surely because I found some wheels on github to use as tests.

If anyone has the bandwidth to clean up the tests a little bit -- even just remove the failing test -- that would be great.

[ehashman]

I'll see if I can just remove it for now.

Hi @dvarrazzo, you can now rebase this PR and the build should pass!
