tests/functional: update output of 086

Test 086 is broken by the commit 21549a1 because it changed
the rule of VID allocation. This patch fixes the output.

086 is completely changed for other test in the master branch, because
the limitation of a number of maximum children is already
resolved. This patch is written for stable-0.8.
