main/git: add git-prompt subpackage for git-prompt.sh
Having the git branch in one's prompt is a nice feature; I use it frequently and assume I'm not alone in this. git-prompt.sh is the 'good' way of doing it instead of putting $(git branch --show-current 2>/dev/null) in my PS1, and has lots of other features too, not just branch name.
If Alpine isn't interested in this, feel free to close it.
