render also Require into an pre-apache2.4 vhost if directories['auth_require'] is set

...uire'] is set
@zivis Prior to the fix for MODULES-1294 we did not have any `else` case for requires for apache2.2, and additionally, ```Require all granted``` appears to be apache 2.4 specific. Can you get rid of the else?

Once you've fixed that can you please squash this down to a single commit?

Thanks!
