[glib] Initialise variable in g_time_val_from_iso8601()

[Javier Jardón <jjardon src gnome org>]

commit 2321e5aed07154761223bb124770beba56700e41

    Initialise variable in g_time_val_from_iso8601()
    
    The function does not initialise the struct tm,
    giving it improper values of tm_isdst making the result
    an hour out.
