selftests/bpf: add a test for device cgroup controller
Add a test for device cgroup controller.
The test loads a simple bpf program which logs all
device access attempts using trace_printk() and forbids
all operations except operations with /dev/zero and
/dev/urandom.
Then the test creates and joins a test cgroup, and attaches
the bpf program to it.
Then it tries to perform some simple device operations
and checks the result:
create /dev/null (should fail)
create /dev/zero (should pass)
copy data from /dev/urandom to /dev/zero (should pass)
copy data from /dev/urandom to /dev/full (should fail)
copy data from /dev/random to /dev/zero (should fail)
