Check for save_path maybe broken

[gittoar]

save_path /var/lib/php5 (1733)

phpsecinfo.com says "Pass
save_path is enabled, which is the recommended setting. Make sure your save_path path is not world-readable
Current Value: /var/lib/php5
Recommended Value: A non-world readable/writable directory
More information »".

SecurityInfo says "unable to retrieve file permissions on save_path".

So the SecurityInfo does not check the return-codes/-infos from phpsecinfo.com properly or the implementation differs from phpsecinfo.com. This is confusing and should be corrected and more documented for minimum debugging purpose. Thanks.
