tipc: Update maintenance information

Updates TIPC maintenance information to reflect changes that have
taken place during TIPC 2.0 development, including:

- removal of directories that have been deleted
- removal of websites that have been decommisioned
- removal of sidestream SCM repositories that are no longer used
- addition of netdev as appropriate list for kernel code.

Grateful acknowledgement is given to Joe Perches <joe@perches.com>,
who reported the stale file entry that triggered the update.
