xen.inc: python 3.12: fix datetime deprecation warning

Browse Source 
Parsing xen.inc with a host distro that provides python 3.12 (such as Ubuntu
24.04) generates the following deprecation warning:

DeprecationWarning: datetime.datetime.utcfromtimestamp() is deprecated and scheduled for removal in a future version.
Use timezone-aware objects to represent datetimes in UTC: datetime.datetime.fromtimestamp(timestamp, datetime.UTC)

This warning comes from the use of datetime.datetime.utcfromtimestamp()
in get_build_time_vars.

datetime.UTC seems to be a getter wrapper for datetime.timezone.utc,
which is already available on older host distro python versions
(I have tested only with python 3.10 provided by Ubuntu 22.04)
so, opt to use that instead to prevent a breaking change.
