Added chmod 777 for phpmyadmin tmp folder

Without chmod 777 for /var/lib/phpmyadmin/tmp, uploading a sql database through phpmyadmin generates the next errors:

"Failed to load /etc/phpmyadmin/config-db.php Check group www-data has read access and open_basedir restrictions., 

PHP Warning:  Unknown: open_basedir restriction in effect. File(/tmp) is not within the allowed path(s): (/usr/share/phpmyadmin/:/etc/phpmyadmin/:/var/lib/phpmyadmin/:/usr/share/php/php-gettext) in Unknown on line 0

PHP Warning:  File upload error - unable to create a temporary file in Unknown on line 0"
