selftests/bpf: add wrong type test to cgroup dev
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.
