WIP: Take a stab at Raspbian

[JohnnyMarnell]

Almost working, raspbian successfully builds and boots with qemu, however with a different kernel.

• Take a stab at a raspbian build
• Fix intermittent fails because of docker run -it bug in Makefile
• Attempt OS detect and make it work for Docker for Mac (was dying because losetup DNE, have to attach to the Hypervisor to see the loopback via docker nsenter image)
• Minor bash arithmetic change in create_image.sh
• Add .gitignore
• See wip*sh ... There is an example of fetching a kernel, dtb (don't know what this is), and Raspbian image that works with qemu-system-arm (googled this). I atried to apply that to the kernel I think I built but it hangs. It does seem to boot to the fs built with a different kernel.

This. Is. So. Cool. Haha, it's exactly what I want, I'm trying to get it to work with Raspbian + qemu. I think (?) I'm close but could use some help, this is all above my pay grade.

Hi @JohnnyMarnell, thanks a lot for your contribution! I'm fine with merging it when/if it's done. Unfortunately, I cannot help here myself due to lack of time & Raspberry Pi experience.

Thanks for the reply, I think qemu / ARM adds too many layers to figure out, giving Packer a try at the moment. (And missing Docker layer caching for sure lol).
