lib/test_ubsan.c: VLA no longer used in kernel

Browse Source 
Since we now build with -Wvla, any use of VLA throws a warning.
Including this test, so...  maybe we should just remove the test?

  lib/test_ubsan.c: In function 'test_ubsan_vla_bound_not_positive':
  lib/test_ubsan.c:48:2: warning: ISO C90 forbids variable length array 'buf' [-Wvla]

For the out-of-bounds test, switch to non-VLA setup.

  lib/test_ubsan.c: In function 'test_ubsan_out_of_bounds':
  lib/test_ubsan.c:64:2: warning: ISO C90 forbids variable length array 'arr' [-Wvla]
