They are flagged by lgtm.com. Avoid the warning by dropping unused
includes.

First of all, the "os.setuid()" call is never reached. lgtm.com warns about
that, and warnings are annoying because they require investigation.

This code is only in the example, so that the user would understand that
they should edit the source and set the desired UID. But you can only
call setuid() if you have CAP_SETUID, so commonly this anyway doesn't
work -- unless you are root already, and then you actually don't need
it either.

Let's drop this code from the example.

Maybe this example really should be dropped. Does the "dbus" python
module even still work? Doesn't for me...

input() in Python2 evaluated the string and was thus unsafe. On
Python2, the right choice is raw_input. In Python3, input does
what raw_input did.

Work around this.

The main "problem" is that lgtm.com flags this as error. The fix
in the example is not important, but getting a low number of warnings
is.
