Expand the binary stats test to verify that a stats fd can be dup()'d and read, to (very) roughly simulate userspace passing around the file. Adding the dup() test is primarily an intermediate step towards verifying that userspace can read VM/vCPU stats before _and_ after userspace closes its copy of the VM fd; the dup() test itself is only mildly interesting.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
