platform: include "linux-headers" via "libnm-std-aux/nm-linux-compat.h"

We have our own copy of linux kernel headers, and we must never
directly include the corresponding versions from the system.

Avoid that, by only including the clones via "libnm-std-aux/nm-linux-compat.h"
and by including the compat wrapper header before other system headers.
