[sheepdog] [PATCH RFC 1/5] sheep: add nid_to_str() for formatting node id from sockfd subsystem

[Hitoshi Mitake]

From: Hitoshi Mitake <mitake.hitoshi at gmail.com>

sockfd subsystem only has node_id for representing node of each sockfd
entry, so it cannot use node_to_str() for formatting node id. This
patch implements a new function nid_to_str() for sockfd
subsystem, and make node_to_str() a wrapper for it.
