[tz] DST cancelled for Asia/Baku since 17 March 2016

Hi, I couldn't find a reference for this change from 17/Mar/2016 to be implemented in any tzdata revision. I did see that there was a minor correction for Asia/Baku in 2016e DB (for 1992), but not for the change from 2016 and on. Source https://www.timeanddate.com/news/time/no-dst-azerbaijan.html BR, Ariel
