devtool: update-recipe: add handling for git recipes
When updating git-based recipes, in a lot of cases what you want is to
push the changes to the repository and update SRCREV rather than to
apply patches within the recipe. Updating SRCREV is now the default
behaviour for recipes that fetch from git, but this can be overridden
in both directions using a new -m/--mode option.
