[glib] win32: fix tests/sources.c

[Dieter Verfaillie <dieterv src gnome org>]

commit a3655be2111ee38839fe2a1fd001923d1d4ad7be
Author: Dieter Verfaillie <dieterv optionexplicit be>

    win32: fix tests/sources.c
    
    "make check" was failing on sys/resource.h not being available on
    win32. Seeing that this test just spews some numbers on stdout
    whithout really testing anything we can safely replace them with
    similar enough numbers by relying on g_get_monotonic_time ().
