ACLs on service users should be ignored because of randomised node names

The creation of service users via reponit creates randomised node names, for example, something like

/home/users/system/communities/7w6ebrYBWEGY5r5cHQ-E [social-enablement-replication-user]

This means than ACLs cannot be set later on that node name if the content package tries to set some ACLs on

/home/users/system/communities/social-enablement-replication-user

This means that we should currently ignore ACLs for service users, that is, nodes with primary type rep:SystemUser like.

Which means in the repoinit section, the following 2 lines should for example be removed: 

create path (sling:Folder) /home/users/system/communities/social-enablement-replication-user
allow jcr:all on /home/users/system/communities/social-enablement-replication-user
