Milan 8f1163a400 Add support for BPF_PROG_TYPE_CGROUP_DEVICE
Kernel 4.15 added a new eBPF program that can
be used with cgroup v2 to control & observe device
access (e.g. read, write, mknod) - `BPF_PROG_TYPE_CGROUP_DEVICE`.

We add the ability to create these programs with the `cgroup_device`
proc macro which creates the `cgroup/dev` link section. Device
details are available to the eBPF program in `DeviceContext`.

The userspace representation is provided with the `CgroupDevice`
structure.
