[PATCH v2 1/4] git-gui: Move revert confirmation dialog creation to separate function

[Pratyush Yadav <me@yadavpratyush.com>]

Upcoming commits will introduce reverting lines and hunks. They also
need to prompt the user for confirmation. Put the dialog creation in its
separate function so the same code won't be repeated again and again.
