[PATCH v2] error-report: fix g_date_time_format assertion

[Haiyue Wang <haiyue.wang@intel.com>]

The 'g_get_real_time' returns the number of microseconds since January
1, 1970 UTC, but 'g_date_time_new_from_unix_utc' needs the number of
seconds, so it will cause the invalid time input:

(process:279642): GLib-CRITICAL (recursed) **: g_date_time_format: assertion 'datetime != NULL' failed

Call function 'g_date_time_new_now_utc' instead, it has the same result
as 'g_date_time_new_from_unix_utc(g_get_real_time() / G_USEC_PER_SEC)';

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

v2: use 'g_date_time_new_now_utc' directly, which handles the time
    zone reference correctly.
