    selftest: Add some tests for linked attribute conflicts
    
    Currently we have tests that check we can resolve object conflicts, but
    these don't test anything related to conflicting linked attributes.
    This patch adds some basic tests that checks that Samba can resolve
    conflicting linked attributes.
    
    This highlights some problems with Samba, as the following tests
    currently fail:
    - test_conflict_single_valued_link: Samba currently can't resolve a
      conflicting targets for a single-valued linked attribute - the
      replication exits with an error.
    - test_link_deletion_conflict: If 2 DCs add the same linked attribute,
      currently when they resolve this conflict the RMD_VERSION for the
      linked attribute incorrectly gets incremented. This means the version
      numbers get out of step and subsequent changes to the linked attribute
      can be dropped/ignored.
    - test_full_sync_link_conflict: fails for the same reason as above.
