Subject: [PATCH] Clean up superfluous import from extern prelude

Our dependencies get passed to rustc with '--extern' (see output of
'cargo --verbose check') and starting with the 2018 edition, they are
automatically provided trough the extern prelude
(https://doc.rust-lang.org/stable/reference/names/preludes.html#extern-prelude).

So no need for declaring the use explicitly here. Current nightly
reports this as unused import and this silences the warning.
