[PATCH] tst-getdents64.c: Mark as UNSUPPORTED when compiled with Clang

[H.J. Lu]

Since Clang doesn't support variable length array in structure:

./sysdeps/unix/sysv/linux/tst-getdents64.c:118:18: error: fields must have a constant size: 'variable length array in structure' extension will never be supported
  118 |             char buffer[buffer_size];
      |                  ^

Mark tst-getdents64.c as UNSUPPORTED when compiled with Clang.
