Fix error about missing attribute 'timeout' that happens sometimes during compilation

The fix [1476:49f1763a5613] of the problem with following trace was wrong.
Traceback (most recent call last):
File "./Beremiz.py", line 1229, in run_with_except_hook
run_old(*args, **kw)
File
"/home/developer/WorkData/PLC/beremiz/beremiz/util/ProcessLogger.py",

"/home/developer/WorkData/PLC/beremiz/beremiz/util/ProcessLogger.py",
line 169, in finish
if self.timeout: self.timeout.cancel()
AttributeError: ProcessLogger instance has no attribute 'timeout'
The problem was that compilation process was finished before the timeout attribute is set.
Now timeout is set before launcing of compilation process.
