Our best guess is that the two syntaxes should have exactly equivalent effects, so, let's be consistent with what we do in libcxx/include/. I've left `#include "include/x.h"` and `#include "../y.h"` alone because I'm less sure that they're interchangeable, and they aren't inconsistent with libcxx/include/ because libcxx/include/ never does that kind of thing. Also, use the `_LIBCPP_PUSH_MACROS/POP_MACROS` dance for `<__undef_macros>`, even though it's technically unnecessary in a standalone .cpp file, just so we have consistently one way to do it.
