twister: fix timeout status for the device handler

Currently in binary handler and qemu handler we have status `failed`
in case of test timeout, but in device handler we have status `error`

This not only adds inconsistency between handlers, but also prevents
us from usage test retry functionality for the runs on HW.

Fix timeout status by changing it to `failed` instead of `error`.
