SoH: Add all the mandatory attributes into SSoH vendor specific attribute

This adds all the attributes that are marked as mandatory for SoH in
IF-TNCCS-SOH v1.0. MS-Machine-Inventory does not contain correct data
(i.e., all version fields are just marked as inapplicable) and
MS-MachineName is hardcoded to wpa_supplicant@w1.fi for now.
