Jan Kaluza d9914ff27d Fix the fd leaking to aardvark-dns. ...

The openDirectory function is missing the unix.O_CLOEXEC flag.
As a result, this file descriptor can leak into the aardvark-dns
process which can then block the umount of rootfs - in this case,
the umount fails with "Device or Resource busy" error message.

This commits adds the unix.O_CLOEXEC to unix.Open call, resulting
in this fd to be closed on aardvark-dns exec.
