x86/time: Update wallclock in shared info when altering domain time offset
domain_set_time_offset() udpates d->time_offset_seconds, but does not correct
the wallclock in the shared info, meaning that it is incorrect until the next
XENPF_settime hypercall from dom0 which resynchronises the wallclock for all
domains.
