server/process: Ensure logging is flushed

The cookerlog output goes to a file and its misleading to look at it and
not have it up to date with what the cooker is actually doing. Ensure
written data is flushed.

Ultimately this should be using python's logging but that is for another
day, we need simple fixes right now.
