src: force line buffering for stderr

Trott · Fishrock123 · commit 02e012e984f3 · 2015-11-11T12:11:34.000-05:00
SmartOS does not line buffer stderr by default, or at least that is the behavior on the Node project Jenkins server. Force line buffering. This resolves the flakiness observed on SmartOS for test-debug-signal-cluster.
