    Fix prechecks in check mode

    When running in check mode, some prechecks previously failed because
    they use the command module which is silently not run in check mode.
    Other prechecks were not running correctly in check mode due to e.g.
    looking for a string in empty command output or not querying which
    containers are running.

    This change fixes these issues.
