Deprecated passing null to $value on apache_setenv() in site settings.php template

The cause of this is the templates in Provision/Config/Drupal/provision_drupal_settings_*.tpl.php which writes out the settings.php for each site. Attached updates those to use '' rather than null.

After applying this to provision all effected sites need revalidating in Aegir.

I do wonder if we need some kind of upgrade path here, but that's a bit extreme probably, we can likely just get this in and be done with it.

Many thanks!
