[webkit-dev] New iOS versions sending bogus User-Agent build data

[Ali Juma]

It's worth noting that https://bugs.webkit.org/show_bug.cgi?id=182629 added
back the OS version to the UA string, at least on trunk (the reasons given
there, in https://bugs.webkit.org/show_bug.cgi?id=182629#c6, sound exactly
like those mentioned by Colin in this thread).
