description:
Include namespace.h in a few of libc source files

The NetBSD Standard C Library uses internally some of its functions with
a mangled symbol name, usually "_symbol". The internal functions shall not
use the global (public) symbols.

This change finishes elimination of usage of the global name of the
following symbols:
  - close -> _close
  - execve -> _execve
  - fcntl -> _fcntl
  - setcontext -> _setcontext
  - wait6 -> _wait6
  - write -> _write
  - writev -> _writev
