bitbake: process/cooker: Improve readypipe handling

Issues in start are not being correctly detected by the current readypipe
code. Change it to use specific "ready" or "fail" messages to correctly
determine the correct failure mode and avoid bitbake seeming to hang
(it does currently timeout eventually).
