[Bug] dpkg error installing zenoh-bridge-mqtt in Docker

[JEnoch]

Describe the bug

Similarly to eclipse-zenoh/zenoh#415 , in a Docker container the postinstall script is failing because there is no sudo nor systemctl

To reproduce

1. docker run -it --init ubuntu
2. apt update && apt install -y ca-certificates
3. echo "deb [trusted=yes] https://download.eclipse.org/zenoh/debian-repo/ /" | tee -a /etc/apt/sources.list > /dev/null
4. apt update && apt install -y zenoh-bridge-mqtt

System info

• Docker ubuntu:latest
• Version: 0.10.1-rc
