Update IANA tzdata to 2018c

See http://mm.icann.org/pipermail/tz-announce/2018-January/000048.html
for details. Most notable is that Brazil will start DST (UTC-3 => UTC-2 in
São Paulo) on the 1st Sunday of November instead of the 2nd Sunday of
October.

In JS console:
> new Date(Date.UTC(2018, 9,31, 5)).toLocaleString("en", {timeZone: 'America/Sao_Paulo'})
"10/31/2018, 2:00:00 AM"
> new Date(Date.UTC(2017, 9,31, 5)).toLocaleString("en", {timeZone: 'America/Sao_Paulo'})
"10/31/2017, 3:00:00 AM"
