Bug 1517228: perf_to_log function amd misisng data

Because some systems may not have all the available data we should
check if the data exists before trying to display it.

To test:
Before patch change the line in lib/mahara.php
if (function_exists('posix_times')) {
to
if (!function_exists('posix_times')) {

and make sure the 'perf_to_log' config option is set to true

This will cause the errors we are trying to deal with to show up
