This is a follow up adjustment to commit6c92bd5cd4("selftests/bpf: Test_progs indicate to shell on non-actions"), that returns shell exit indication EXIT_FAILURE (value 1) when user selects a non-existing test. The problem with using EXIT_FAILURE is that a shell script cannot tell the difference between a non-existing test and the test failing. This patch uses value 2 as shell exit indication. (Aside note unrecognized option parameters use value 64).

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.
