varLib: initialize all fields to None in new empty GDEF

Browse Source 
code elsewhere assumes that all optional fields in OT tables are initialized
to None (that is the case when decompiling from a file).
This patch makes sure that the new GDEF table build by varLib when creating
a new VF is properly initialised.
Ideally we wouldn't have to do that manually, but the constructor would
take care of that. But otData-generated classes are special...
