netlink_route_socket: add new nlmsg_readpriv perm
Used when mapping RTM_GETLINK messages to this new permission.
Users of netlink_route_sockets that do not use the net_domain()
macro will need to grant this permission as needed. Compatibility
with older vendor images is preserved by granting all vendor domains
access to this new permission in *.compat.cil files.
Bug: 141455849
Test: build (this change is a no-op without kernel changes)
