Fixed issue with Entity Risk Scoring Management page due to recent EUI (

elastic#195666)

## Summary

After the most recent EUI upgrade
[here](elastic#194619), the Security
Entity Risk Scoring Management page had significant spacing issues with
regards to the page header. This PR alleviates those issues, and also
simplifies the DOM structure for that component a bit.
