Set `primary_source` for idenfitier in add3prf.py
In METADATA (go/thirdparty/metadata) there is an identifier required for
each package. Our script currently contains 2 identifier and therefore
it's unclear where we actually downloaded the package from.
Therefore, we need to set a `primary_source` marker. To quote the docs:
> The identifier that is the source of truth for the package should be marked with primary_source: true.
