netlink: specs: support generating code for genl socket priv
The family struct is auto-generated for new families, support
use of the sock_priv_* mechanism added in commit a731132424ad
("genetlink: introduce per-sock family private storage").
For example if the family wants to use struct sk_buff as its
private struct (unrealistic but just for illustration), it would
add to its spec:
kernel-family:
headers: [ "linux/skbuff.h" ]
sock-priv: struct sk_buff
ynl-gen-c will declare the appropriate priv size and hook
in function prototypes to be implemented by the family.
