[libc++] Don't make libc++ headers system headers in the modulemap (#205509)
We currently have `[system]` attributes in the modulemap, which
automatically makes the headers inside the module system headers. This
disables warnings when running the tests, which we generally don't want.
We also already have `#pragma GCC system_header` everywhere and use
`-isystem`, so there isn't much need for the tag in the modulemap as
well.
