Remove dependency to docker.io (#985)

* Remove dependency to docker.io

The dependency was basically added since this is needed to spawn up
ursim. However, the start_ursim script catches the case that no docker
executable is available and the tests requiring it are behind a compile
definition which is off by default.

So, in order to not install docker for users automatically, the dependency
shall be removed.

(cherry picked from commit 585e29f)
