gdb.rocm/watchpoint-basic: add gfx1103 to XFAILs

Again, a confirmed KFD issue.  By confirmed, I mean that if a dummy
dispatch is done first, then everything goes OK.

  __global__ void dummy () {}

  int main (...)
  {
    ...
    dummy<<<1, 1>>> ();
    /* Break after malloc.  */
    kernel<<<1, 1>>> (global_ptr1, global_ptr2);
    ...
  }
