ui/vc-gutter: disable git-gutter in some modes

Browse source 
Disabling git-gutter in fundamental-mode theoretically reduces the
number of times git-gutter is initialized (because it has to switch to
and from fundamental-mode once, sometimes twice, when changing major
modes).

git-gutter also has trouble with org-indent-mode, so we disable it
there.

And it isn't useful in image-mode.
