System integration >= 1.47.0 breaks Elastic Agent 7.17.x

Versions of the system integration >= 1.47.0 are incompatible with Elastic Agent 7.17.x but are allowed to be installed.

Steps to reproduce:

Start a 8.13.0 stack:

```
elastic-package stack up -d -v --version "8.13.0"
```

Go `Management->Fleet`, create a policy with a system integration, click `Add agent`

Install and enroll a 7.17.19 agent:

```
sudo ./elastic-agent install --insecure --url=https://fleet-server:8220 --enrollment-token=
```

Run the status command after a few minutes and you'll see that Filebeat got stuck in `Updating configuration`

Looking at the logs (Linux path) you'll see:

```
sudo cat /opt/Elastic/Agent/data/elastic-agent-*/logs/default/filebeat-json.log* | grep error | jq .
```

```json
{
"log.level": "error",
"@timestamp": "2024-03-27T16:31:00.737Z",
"log.logger": "centralmgmt",
"log.origin": {

},
"message": "Error creating runner from config: the processor action syslog does not exist.

which is coming from this config block:

```sh
sudo cat /opt/Elastic/Agent/data/elastic-agent-*/state.yml | grep -B 30 -A 5 'syslog:'
```

This change is coming from this PR https://github.com/elastic/integrations/pull/8103

I suppose the main problem here is that the system integration has no condition for the agent versions:

and nothing prevents incompatible versions of the system integration from being installed on 7.17.x
