Cleaning up TODO's. If we're on >= 5.11 we need userxattr so check the kernel version to skip the manual check via mounting. It feels odd to use contrib/seccomp here but the alternative is pulling that kernel parsing code out into the main pkgs. Another is using the moby parser but that's in moby/moby which is also a dep we don't want here..
