Python2 had old-style classes (no "(object)"), and new style classes (with
"object"). Under Py3 this is a noop, so let's drop it to make the code
a bit shorter.
https://bugzilla.redhat.com/show_bug.cgi?id=1903583 sports the following traceback:

BrokenPipeError: [Errno 32] Datenübergabe unterbrochen (broken pipe)
If logging fails because somebody closed the output pipe, this is not an error.
Let's just ignore this this silently.
I removed the two .flush() implementations because those two classes inherit
from Stream.

I assume that the user had two calibre instances started, and they raced on
the check and creation of the directory. Let's use os.makedirs(exist_ok=True).
(added in Python 3.2).
Also, only create the directories when saving/reading the file, not when the
module is imported.
