Previously, invoking an UNIX agent while enabling DISABLE_CACHING did not work properly. For instance, the invocation DISABLE_CACHING='true' check_mk_agent.linux would result in agent output such as:

'<<<chrony>>>'; waitmax 5 chronyc -n tracking | cat || true

The agents will now run the commands instead of printing them. This regression was introduced in Werk #12906. Thank you Artem Sidorenko for this contribution.
