[ Upstream commit 3220fb667842a9725cbb71656f406eadb03c094b ]
This is a follow up adjustment to commit 6c92bd5cd465 ("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).
Fixes: 6c92bd5cd465 ("selftests/bpf: Test_progs indicate to shell on non-actions")
