Current cgroup_dev test mostly tests that device operation is accepted or
refused base on passed major/minor (and so, any operation performed during
test involves only char device)

Add a small subtest ensuring that the device type passed to bpf program
allows it to take decisions as well.

selftests/bpf: convert test_dev_cgroup to test_progs 2024-07-31T17:00:20+00:00 Alexis Lothoré (eBPF Foundation) alexis.lothore@bootlin.com 2024-07-31T06:37:26+00:00 d83d8230e415ecf727f6b88c0ae55193f149d650 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.
