Only run AppVeyor tests for Windows 64-bit, and not also 32-.

AppVeyor does provide us quite a bit of value at no cost since we're
open-source software, but with only a single container at our disposal
under that plan, our build queue is often maxed-out for hours.

Since most Meteor developers are using 64-bit platforms, the 64-bit
tests provide the most value.  Meteor doesn't have much (if any?) in the
way of 32-bit/64-bit exceptions so any functionality difference would be
at the OS level.  Some day, we might bring this back.
