[sheepdog] [PATCH] sheep: set the length of response in local_get_store_list()

[Hitoshi Mitake]

The commit: 55a84a160dca3c8ed656e21d85fbe93c82e731a9 reduced the
setting of default length of response, so the result of
local_get_store_list() wasn't sent to collie.

Current output of "collie cluster format -b asdf" is:
using backend asdf store
Format failed: Targeted backend store is not found
Available stores:
---------------------------------------

Correct output is:
using backend asdf store
Format failed: Targeted backend store is not found
Available stores:
plain farm
---------------------------------------

This patch let local_get_store_list() set the length of response.
