[sheepdog] [PATCH v2] lib: choose a correct output in logger

[Hitoshi Mitake]

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

Current logger chooses stderr as an output of logs in cases
logarea_init() isn't called or default formatter is used.

This patch lets logger choose stderr when a priority of logs is less
than or equal to LOG_NOTICE. If the priority is larger than or equal
to SDOG_INFO, stdout is used.
