test-list: Fix false-positive build failure with GCC 12.

Browse Source 
GCC 12.2.1 on Fedora 36 generates the following false-positive
warning that is treated as error with -Werror:

 tests/test-list.c: In function 'test_list_construction':
 tests/test-list.c:110:9: error: 'values' may be used uninitialized
   110 |         check_list(&list, values, n);
       |         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~

For some reason it fails to recognize that array will not
be used if 'n' equals zero.

Fix that by just initializing arrays in full before using,
since it's just a test code.
