glib-2.0: fix g-file-into modification time test

The GFileInfo modification time test assumed that the difference between
a modification timestamp in seconds and in microseconds must be greater
than 0.

Mathmatically, there's a one-in-a-million chance that it will be 0.  It
turns out that one-in-a-million chances happen approximately once every
fortnight on the autobuilder.

+Subject: [PATCH] gio/tests/g-file-info: don't assume million-in-one events
+ don't happen
+
+The modification time test creates a file, gets the modification time in
+seconds, then gets the modification time in microseconds and assumes
+that the difference between the two has to be above 0.
+
+As rare as this may be, it can happen:
+
+$ stat g-file-info-test-50A450 -c %y
+2021-07-06 18:24:56.000000767 +0100
+
+Change the test to simply assert that the difference not negative to
+handle this case.
