* Add rmdir, mkdir -p and umask to d8 on Unix.

* Remove the non-working methods from the os object on d8 on Windows
so you can test for their presence with if (os.system).
* Add a test (not run by default since it only works on d8).
* Fix incorrect use of wait that left defunct processes (zombies).
