Clean up: refresh the help text for Kconfig items related to the sunrpc
module. Remove obsolete URLs, and make the language consistent among
the options.

help
- Provides kernel support for querying rpcbind servers via versions 3
- and 4 of the rpcbind protocol. The kernel automatically falls back
- to version 2 if a remote rpcbind service does not support versions
- 3 or 4.
+ RPC requests over IPv6 networks require support for larger
+ addresses when performing an RPC bind. Sun added support for
+ IPv6 addressing by creating two new versions of the rpcbind
