Fix FTBFS issue

Athos Ribeirorequested to merge
athos/mdevctl:ftbfs into debian/master

Hi,

This MR addresses #1050521 by adjusting the env_logger dependency pinned version.

Moreover, it enables running the upstream test suite during build time through dh_cargo (https://salsa.debian.org/rust-team/dh-cargo/-/blob/master/cargo.pm).

Finally, I am also bumping the standards version here.
