fix(static_obstacle_avoidance): ego doesn't keep stopping in unsafe condition

[satoshi-ota]

Description

Bug: The ego couldn't keep stopping in front of the avoidance target during yielding. This issue was caused by #9089.

The purpose of #9089 was removing stop line and preventing stuck when the ego obiously overrun the stop line. But it removed stop line even when it stopped properly since threre is no buffer.
