Update timezone db to 2016i

Turkey decided to stop DST and to stay in UTC+0300 year around. Without
this change, Chrome is 1-hr off in Europe/Istanbul.

This is updating ICU 56.1 for M55 branch.

BUG=664126

(new Date("10/30/2016 12:00Z")).toLocaleString("en", {timeZone: "Europe/Istanbul"})
"10/30/2016, 3:00:00 PM"
