Denton Liu 6c22d715e7 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.
