UPSTREAM: net: align SO_RCVMARK required privileges with SO_MARK

The commit referenced in the "Fixes" tag added the SO_RCVMARK socket
option for receiving the skb mark in the ancillary data.

Since this is a new capability, and exposes admin configured details
regarding the underlying network setup to sockets, let's align the
needed capabilities with those of SO_MARK.
