Update timezone data files to 2011n 

This will update timezone data to the latest. Among other things, Moscow time 
should be *always* 4 hrs ahead of UTC.

While doing so, I'm fixing the timezone name for US Pacific time in Korean locale. There's a typo.  

As for MSK having 'Moscow Summer Time/Moscow Standard Time' in zone files,
it should not hurt. As long as DST is not used any more, we'll not get
'Moscow Summer Time' in our UI.

This CL will be follwed by actual data file updated for all the
platforms we care about. 

BUG=74566,chromium-os:23256
TEST=Change the timezone to MSK (Moscow timezone) during winter. It should be UTC+4:00 instead of UTC+3:00
