vm: hyperv: make hw clock friendlier to windows

This patch sets the local time as windows reportedly
expect. According to libvirt docs:

" Most operating systems expect the hardware clock to
be kept in UTC, and this is the default.
Windows, however, expects it to be in so called 'localtime'."
http://libvirt.org/formatdomain.html#elementsTime

This is the reccommended setting for windows and reportedly
has stability benefits for live migrations.

The new setting is enabled on top of the hyperv optimizations,
and is disabled by default for backward compatibility.
