Native assemblies aren't found for Libuv

[bojanrajkovic]

Steps to Reproduce

1. Download and open this workbook: https://gist.github.com/bojanrajkovic/78a2bf942f19c6e5973aa0bb34f4bd61
2. Comment out the code that calls LoadLibrary on libuv.dll
3. Run workbook

Expected Behavior

Server starts, requests complete.

Actual Behavior

Server does not start because it can't find libuv. Libuv needs to be added in NativeDependencyResolver's special cases until such a time as we implement generic native dependency loading.
