check_ambari_permissions.py does not run for all the files and directories listed

ambari-server/src/main/resources/scripts/check_ambari_permissions.py script introduced in branch 2.5.0 and published here (https://cwiki.apache.org/confluence/display/AMBARI/Ambari+Vulnerabilities#AmbariVulnerabilities-FixedinAmbari2.5.0) to solve Public Vulnerability:
https://nvd.nist.gov/vuln/detail/CVE-2017-5642
only works partially.
There is a bug and it will only handle the last directory/file when there are multiple directories/files listed.
So the vulnerability is not totally resolved.
For example files under /etc/ambari-server/conf/ such as ambari.properties are not revised
