    resolv: Fix building tst-resolv-invalid-cname for earlier C standards
    
    This fixes this compiler error:
    
    tst-resolv-invalid-cname.c: In function ‘test_mode_to_string’:
    tst-resolv-invalid-cname.c:164:10: error: label at end of compound statement
         case test_mode_num:
              ^~~~~~~~~~~~~
    
    Fixes commit 9caf782276ecea4bc86fc94fbb52779736f3106d
    ("resolv: Add new tst-resolv-invalid-cname").
