Add default Yara paths to avoid long scans

[paralta]

Description

Currently, the Yara scanner might take more than one hour to scan an asset in AWS and GCP. Additionally, in Azure the scan never finishes. This can be avoided by limiting the list of paths that Yara needs to scan.

Steps to Reproduce

1. Run a scan with the Misconfiguration family enabled
2. Wait for scan to be over
