netlink: specs: mptcp: clearly mention attributes

The rendered version of the MPTCP events [1] looked strange, because the
whole content of the 'doc' was displayed in the same block.

It was then not clear that the first words, not even ended by a period,
were the attributes that are defined when such events are emitted. These
attributes have now been moved to the end, prefixed with 'The defined
attributes are' and ended with a period.
