KaiOS: be more careful detecting the presence of KaiAds

Browse Source 
Now that we catch JavaScript errors and report them to the user, I could
tell that the way we were detecting the presence of getKaiAd() didn't
work because it caused an alert every time a build without KaiAds was
started.  Detecting the presence of a global variable is slightly
tricky, but explicitly looking for it on "window" works and isn't very
ugly.
