logger: align custom non-English logger functions with stdlib
Specifically, this adds *args, **kwargs to them. The stdlib logging
functions are used when the language is detected as English. Having
them aligned avoids bugs like #1396, where a valid stdlib logging call
caused a fatal error on a non-English installation.
(I have tested this by adding LC_ALL=de_DE to my development
instance's environment and reverting 457fceb0 (the fix for #1396):
without this patch, the reported error occurs; with this patch, Mylar
starts up just fine.)
Fixes: #1398
