kernel: native_posix: Don't run global C++ constructors

On the native_posix board global object constructors
are run by the underlying OS runtime init prior to
Zephyr kernel init. Thus Zephyr should not run global
object constructors a second time. Doing so breaks
application behavior that relies on global
constructors doing work that must be done only once.
See bug #36858 for more information.
