Resolve SD Card Image Creation

[CalebProvost]

DoD: Fix SD Card Image creation (blocker to #15 (comment))

[CalebProvost]

Oddly enough... Fresh build results in an image being created... I think the preexisting tools might have an issue with creating an image if one already exists. Inserted a test which will remove the image first before making it.

Testing now.

[CalebProvost]

It doesn't appear to be an actual issue... It'll fail inside the docker container... sometimes...
I think we'll need to not automate this step in order to have this step work...
Or... Automate this step outside of the docker container...

I'll work on extracting this step from the docker script and instead insert it into a script which will trigger each docker execution, then the sd card creation.

[CalebProvost]

I still have yet to determine the reasoning, but the dosdcard.sh script we're using to create the tegra's sd card image doesn't want to hand off the GPT information to the tegrra210-flash-helper.sh script which creates our image. However, because it does work outside of docker, I'll write the all-integrated-run script to to do a docker container run to build the tegra image, then do the do sd card image, then back to docker to flash the arduino with it's needed firmware.

[CalebProvost]

On second thought... because the tegra build takes so long, I'll have the integrated script do the arduino work via docker 1st, then do the tegra image via docker, then (outside of docker) create the sd card image. That way a user can unplug the arduino and wait for the tegra stuff without having to wait for hours if the arduino has issues.

Potential new build script for yocto:

Looks like there's a tegraflash helper script it's calling that needs bash -x? You need to trace wherever it's failing and add some debug information there, either with bash -x or echo statements or whatever.
