Move git_init check into it's own block under have_git

[onlyhavecans]

This allows gitignore to be generated even if we don't wish to initialize the cookbook as it's own git repo
This is a quick fix for Issue #145

I'm not 100% sure but this likely falls under Obvious Fix policy.

Thanks for the patch @tbunnyman. I'm wondering if we should move the code in here, into an only_if block to the execute resource.

Also as curry mentioned we will need a CLA form you to get this further. Sometime curry can make mistakes. Let's know if this is one of those cases as well.

I think the change originally fell under Obvious Change but I went through the procedure of linking everything and making the signature either way�.

I just modified the if block because it preserves the style.

I looked over the generator command and the other ones in the app and I'm not sure exactly what you have in mind. In all other places the execute blocks are in the recipe's themselves and the generators seem to just set variables called in the recipes.

Changing the execute blocks to use not_if and only_if is trivial but other recipes still use the if blocks.
