[sheepdog] [PATCH] configure: disable tracer for 0.4.0 release

[Liu Yuan]

From: Liu Yuan <tailai.ly at taobao.com>

Current tracer can't work with fully dynamic(short) worker threads due to its
per thread ring buffer implementation, as it can in fact only work with static
threads.

Some of its infrastructure needs rewriting to adopt it to short threads. For now
let's disable it.
