htmlpurifier sets different permissions in dataroot

[Simon Coggins]

Currently HTML purifier uses its own default directory and file permissions when creating files in dataroot, instead of respecting those given by $CFG->directorypermissions. That can mean some files generated have stricter permissions than specified.

To reproduce:

1. Create a config.php file with $cfg->directorypermissions = 0777
2. Install a mahara site via the command line CLI script
3. Visit the homepage of the site in a browser
4. View the dataroot folder and look at the file permissions

You will notice that most folders have 777 permissions but the subdirectories inside htmlpurifier/ have 755.

Configure htmlpurifier to use same directory permissions as Mahara (Bug #1333071)

This is needed to ensure the permissions of files/folders in dataroot
are correct for unit testing
