difftool: fallback on merge.guitool
In git-difftool.txt, it says
'git difftool' falls back to 'git mergetool' config variables when the
difftool equivalents have not been defined.
However, when `diff.guitool` is missing, it doesn't fallback to
anything. Make git-difftool fallback to `merge.guitool` when `diff.guitool` is
missing.
