Check for user_id and group_id maybe broken

[gittoar]

User-ID: 33
Group-ID: 33

Yes, it is lower than 100 and therefore an issue but due to restrictions via PHP disable_functions the checks don't work via phpsecinfo.com, i.e. "Not Run
Functions required to retrieve group ID not available".

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.

I'm seeing this warning because PHP is running as UID and GID 48 (user apache).

/**
 * the minimum "safe" UID that php should be executing as.  This can vary,
 * but in general 100 seems like a good min.
 *
 */
define('PHPSECINFO_MIN_SAFE_UID', 100);

I couldn't find any reference why UIDs less than 100 (besides UID 0) are privileged and unsafe. UID 0-99 is reserved for system users and should not be used by applications according to LSB, but this doesn't automatically make them privileged and unsafe. Please change this test!
