test_dev_cgroup is defined as a standalone test program, and so is not executed in CI. Convert it to test_progs framework so it is tested automatically in CI, and remove the old test. In order to be able to run it in test_progs, /dev/null must remain usable, so change the new test to test operations on devices 1:3 as valid, and operations on devices 1:5 (/dev/zero) as invalid.

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 reStructuredText 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.
