ARROW-1541: [C++] Fix race conditions in arrow_gpu with generated
Flatbuffers files. Do not put generated files in source tree
It's a better practice to put generated files in the build directory rather
than in the main source tree. There was also a race condition with
`arrow/gpu/cuda_version.h`, so fixed that also

> The Arrow GPU/CUDA build has a race condition with the generated Flatbuffers
> files. We must add a dependency so that the Flatbuffers files are compiled
> before the relevant arrow_gpu units are compiled.
> Encountered this when testing 0.7.0 RC0. Because arrow_gpu is alpha I don't
> think this should block
