Rework the generation of the index.json version of the package
indexes to match the original intent (i.e., for use by the ASU
server and other downstream projects). The current file contains
package names that have ABI versioning, making them unusable by ASU,
so we now remove the ABI suffixes.
Also adds a 'version' field to the json, so downstream utilities
can detect the new semantics of the package name fields.

Parse the native package index files into a json file for use by downstream

The "version 1" index.json contained ABI-versioned package names, making the
|
|
unusable by the ASU server. The version 2 format contains package names that
|
|
have been stripped of their ABI version.
