Description

Summary:
In the Apache Sling Starter 13-SNAPSHOT, after upgrading to org.apache.felix.http.jetty 5.1.2 the health checks are no longer served on /system/health.

Steps to Reproduce:

1. Check out https://github.com/apache/sling-org-apache-sling-starter
2. build with mvn clean package
3. run with target/dependency/org.apache.sling.feature.launcher/bin/launcher -f target/slingfeature-tmp/feature-oak_tar.json
4. wait a bit and run http://localhost:8080/system/health.txt

Expected Behaviour:
The health check status should be returned. Instead, the SlingMainServlet responds with a 404.

Additional Details:
Using the web console at http://localhost:8080/system/console/httpservice confirms that th path is served by the Sling Main Servlet.
