mptcp: pm: netlink: announce server-side flag
Now that the 'flags' attribute is used, it seems interesting to add one
flag for 'server-side', a boolean value.
This is duplicating the info from the dedicated 'server-side' attribute,
but it will be deprecated in the next commit, and removed in a few
versions.
