Some ThinkPads failed to suspend to s2idle when ethernet disconnected.

I219 chip of some platforms is controlled by ME, which needs more time

[Regression Potential]
Low, Increase timeout and breaks with condition,
no impacts for who don't need this long wait.

Bionic doesn't introduce the commit f15bb6dde738cc8fa0, no need for
