    gqsort: Move test to glib/tests/
    
    Previously tests existed in two places,
    `$top_srcdir/tests/qsort-test.c` contained a similar test
    to the one in `$top_srcdir/glib/tests/sort.c` called `test_sort_basic()`
    
    The test for checking with zero elements was additional added to
    `$top_srcdir/glib/tests/sort.c` and `$top_srcdir/tests/qsort-test.c`
    was deleted.
    
    Related to: #1434
