Set up Semaphore CI integration

[lmb]

libbcc seems to use Semaphore CI with a custom stage1 to run eBPF unit tests. We can probably do the same.

[lmb]

I've created kinvolk-archives/stage1-builder#30 to update the kernels of the test runner to the latest versions.

@nathanjsweet can you please sign up to semaphoreci.com and let me know your username, so I can add you to the org? You also have to authorize semaphore CI to access this repo, seems like I don't have enough permissions do to that.

Assigning to you for the time being.

[nathanjsweet]

I added it in, but it looks like the build doesn't have enough capabilities to run the test.

[lmb]

Yeah, it needs some custom setup to run the tests in a VM. I've added you as an owner of the new tools org, can you add the ebpf repo to it?

[lmb]

Bump, could you take a look?

@lmb I'm trying to get this working, but I'm having trouble I think I made a good start here:
https://github.com/newtools/ebpf/blob/semaphore/semaphore.sh

But I'm getting rkt errors that, from my perusal of rkt issues, appear to be related to kernel version.
The project is integrated with semaphore ci now, so you should be able to fiddle with the semaphore branch.

I'll take another crack at it later this week.
