vpd source: enable choosing one of many keywords

Invert the property,keyword map. For example, change MACAddress: VINI,B1
to VINI,B1: MACAddress. Change the mako template to handle this.

This will allow us to pick VPD information from one of many
record/keyword combinations that can source an individual property.
