paygen: Deprecate release.conf

This CL removes the usage of crostools.config and
crostools.query from paygen_build_lib. No data
used during payload generation is collected from
the release.conf file.

All accesses of release.conf have been replaced
with querying the data published by goldeneye
in GCS.
