Fixes #4826: correct diplay of AIX LPAR VM type

The only meaningfull correction is on  rudder-web/src/main/resources/default.properties 
All modification on rudder-core/src/test/resources/ldap-data/schema/099-0-inventory.ldif are due to an automatic resynchronisation of openldap schema toward testing schema. They could have only impacted tests, and tests are working fine after it.
