System properties can be abused to get around Treble requirements of
having a clean system/vendor split.  This CL seeks to prevent that by
neverallowing coredomain from writing vendor properties.

Sandeep suggest to re-order the events in that thread,
that should be the right solution,
this change is only a tempory workaround before that change.
