[stable/datadog] Correct handling of processAgent.processCollection setting (#21525)

* Correct handling of processAgent.processCollection setting

This addresses the issue when process agent would terminate if `processAgent.processCollection` was set to `false`.

Setting `DD_PROCESS_AGENT_ENABLED` to `false` results in termination of process agent. To disable process collection we need to leave this env var as not set on this container.
