Fix the timezone detection on Windows with RDP.

This is to cherry-pick fixes from the upstream to fix
the timezone detection issue when a remote Windows
session is used. The detected timezone should be that of
a remote machine Chrome is running on, but without this
fix, it uses the timezone of machine where a RDP connection
originates.
