Makefile: Create .go/bin directory

[dave-tucker]

When checking out the project and running make test it fails as Docker
attempts to mount the .go/bin directory which doesn't exist. This
commit ensures that the directory exists and avoids the error.

That's a good catch @dave-tucker but I have to wonder why dave we not seen it fail before. Our CircleCI runs builds in a completely pristine environment on Linux and we all run builds on Mac OS too.

Can you share what exact set of steps made it fail? Starting from checking out the repo, etc.

[dave-tucker]

Yep. Note that I'm on Windows 10 and developing using Ubuntu on Windows Subsystem for Linux (WSL) so it's a bit of a quirky setup. I have a hunch that it's because of the way that filesharing works in Docker for Windows.

Great -- you're the first one to have that setup with EVE! That's super helpful. Merging your change now.

Btw, do you also have qemu in your setup @dave-tucker ?

Not just yet, but I plan to play around with getting it to work soon
