Support for BPF_PROG_TYPE_CGROUP_SOCK

[theduke]

It seems like there currently is no support for BPF_PROG_TYPE_CGROUP_SOCK, which are different from socketfilter.

I'd especially care about attaching to CGROUP_INET_SOCK_CREATE.

Is there some way to do this manually right now? (Probably not, since redbpf::Program seems to need specific variants)

Would be great to see this implemented.

I think there may be not a simple way to do that manually quickly.. As you concerned the support from redbpf should be made first.. I also want this feature is added to redbpf 👍 Because this feature looks cool!
