[fedfs-utils] [PATCH 4/8] README: Add patent disclaimer language to README

[Chuck Lever]

At IETF 81, NetApp formally announced the existence of a patent which
covers FedFS-related technology:

"US 7,933,921 (April 26, 2011) Referent-controlled location resolution
of resources in a federated distributed system.  Royalty-Free,
Reasonable and Non-discriminatory Licence to All Implementers.
License to be submitted to IETF per usual process."

Split out a new section for IP disclaimers in our README file, and
document the patent.
