[PATCH] error-report: Fix GDateTime usage

[Eric Farman <farman@linux.ibm.com>]

According to the glib manual:

 - g_date_time_new_from_unix_utc() takes a parameter of the number of
   SECONDS since the unix epoch
 - g_get_real_time() returns the number of MICROSECONDS since the
   unix epoch

Rather than convert the latter with G_USECS_PER_SEC, use the convenient
g_date_time_new_now_utc() routine to create the GDateTime object.
This fixes a userspace fault seen when messages get sent to monitor,
such as when a guest is destroyed.

Fixes: 73dab893b569 ("error-report: replace deprecated g_get_current_time() with glib >= 2.62")
