Use newer minitar to support longer symlinks

# tar handling of filenames > 100 characters gets complex. We'd use

This is something I never resolved. It's not actually having any immediate effect, so fixing it is pretty academic. I think the best path forward is to actually depend on the minimum version of minitar directly in this project so we guarantee we get better behaviour.

As I mentioned in the other PR, this will all go away shortly. @NaomiReeves reeves is rolling out chefdk4 shortly over there and then chef-workstation shortly after that.

One could certainly specify a min version in the Gemspec, but I don't think it's worthwhile at this point. the Dk/workstation gemspace is already playing a lot of tricks to get the right versions of gems loaded when needed and jamming in more gems into that space generally tends to make the overlay RPMs/debs that Facebook (and others) build more complicated. Since the DK FB is on is EOL'd and you're about it move off of it anyway, I'd just wait a week or 2, or whatever, and then move on with life. :)
