Ed Maste 2d9ff965b5 bsdinstall: skip tzsetup UTC question
During installation bsdinstall asks (via tzsetup):

> Is this machine's CMOS clock set to UTC?  If it is set to local time,
> or you don't know, please choose NO here!

Most operating systems, except for Windows, use UTC in the hardware
real-time clock by default.  This question from tzsetup is presumably
intended to aid in dual-boot-with-Windows configurations, but these
represent a fraction of all FreeBSD installs.

Rather than asking this question on every install just default to UTC.
Users who want to dual-boot Windows can create /etc/wall_cmos_clock.
We can look at making this smarter in the future.
