Disable this check temporarily.

This is failing for me. When I run the command on my own, I get this:

Error reading /usr/local/google/home/morbo/llvm/llvm.obj/tools/clang/test/Format/Output/.clang-format: Invalid argument
void f() {
  int* i;
  int j;
}

The formatting is like this because I have the Google format version in my
~/.clang-format file. This test should be made independent of that.
