difftool: Fix '--gui' when diff.guitool is unconfigured
When diff.guitool is unconfigured and "--gui" is specified
git-difftool dies with the following error message:
config diff.guitool: command returned error: 1
Catch the error so that the "--gui" flag is a no-op when
diff.guitool is unconfigured.
