[glib: 6/8] Test what happens when GTestSkipCount is 0 or more than number of tests

[Philip Withnall <pwithnall src gnome org>]

commit dfec3c67891745130c5babca1300a180b6f9d059

    Test what happens when GTestSkipCount is 0 or more than number of tests
    
    Using --GTestSkipCount 0 is the same as omitting it. A skip count
    greater than the number of tests is the same as equalling the number
    of tests: they are all skipped.
