net: allow CAP_NET_RAW to set socket options IP{,V6}_TRANSPARENT
Up till now the IP{,V6}_TRANSPARENT socket options (which actually set the same bit in the socket struct) have required CAP_NET_ADMIN privileges to set or clear the option. - we make clearing the bit not require any privileges. - we allow CAP_NET_ADMIN to set the bit (as before this change) - we allow CAP_NET_RAW to set this bit, because raw sockets already pretty much effectively allow you to emulate socket transparency.
