[PATCH next] man: ss.8: add description for SCTP related entries.

[rawal.abhishek92@gmail.com]

From: Abhishek Rawal <rawal.abhishek92@gmail.com>

SCTP protocol support is included, but manpage lacks
the description for its entries. Add the missing
descriptions so that SCTP information is complete.
