[FIX] odoo-bin: server UTC timezone on windows

On UNIX, the timezone modules conversions can be reset by using
`time.tzset()`. On windows this is not available and the timezone (TZ)
environment variable must be set before the first import of time module.

If not, all datetime gotten in python without specifying UTC (such as
datetime.datetime.now) could be wrong.

This was fixed with 4a77c6a0 in 2013, but has come back since 389c2ba97b
imported pkg_resources (which do  a `time` module import) before that.
