Add trustee names back to Windows fileeffectiverights_item, regkeyeffectiverights_item, fileauditedpermissions_item, regkeyauditedpermissions_item

[vanderpol]

Abstract
Several Windows tests had their trustee name removed from the items, because trustee names are not always unique, and the SID should be used for accuracy. However the trustee name and group name should still be included to make the results readable/understandable by human end users. Providing SIDS is accurate, but generally meaningless.

These changes should not impact any existing content, just provide more meaningful results.

Tests:
fileeffectiverights_item: Un-deprecate trustee_name
fileauditedpermissions_item Un-deprecate trustee_name
regkeyeffectiverights_item: Un-deprecate trustee_name
regkeyauditedpermissions_item: Un-deprecate trustee_name
user_sid_item add 'user' and 'group' (from user_item, which this test replaced)
group_sid_item add 'group', 'user' and 'subgroup' (from group_item), which this test replaced).
