Fix builds on systems with RTLD_DEFAULT enabled (#91)

Summary:
The following PR addresses various build issues that occur when GHC does load symbols strictly at build times. exi's did an investigation in #90. GHC on NixOS is compiled with _GNU_SOURCE leading to dlsym using RTLD_DEFAULT, causing strict loading. For hsthrift his means various symbols cannot be found at compile time and error out.

With the following stack I am able to build hsthrift and Glean NixOS. However I have **not** tested it on any other platform just yet (Notable the docker image).

I want to highlight commit 83ed60e, since it moves Utils/Executor.cpp to cpp/Executor.cpp and I am not sure if that's okay.

The rest of the PR should be straight forward.

This is branch includes PR #89 and should cleanly rebase if needed.
