tests: stabilize `test-extdiff.t` on macOS

The recent change in the extdiff extension to take into account whether the GUI
is accessible in d1b54c152673 started triggering this.  I was able to run the
test cleanly without this change at the console, but somewhere along the line, I
read that the CI runner isn't able to access the GUI when not run as the root
user.  This is causing CI failures, so we conditionalize these tests out where
`DISPLAY` is set to a non empty value to force `procutil.isgui()` to be True,
when it in fact doesn't have GUI access.

        self.time = 0
        self.increment = [float(s) for s in increment.split()]
        self.pos = 0

    def __call__(self):
        self.time += self.increment[self.pos % len(self.increment)]
        self.pos += 1
        return self.time
