models: Add description and last_sync_ts columns for Package

description we will get from package.g.o per-package detailed json,
last_sync_ts will be used to record when that detailed json was
last pulled, so that we can rate-limit as-needed.

If still using sqlite, can DROP TABLE package; and re-create with
./manage.py init
or add the columns manually
ALTER TABLE package ADD COLUMN description VARCHAR(500);
ALTER TABLE package ADD COLUMN last_sync_ts TIMESTAMP NOT NULL;

though that NOT NULL vs default on sqlalchemy's side for now might
pose an issue, solving of which is an easy exercise for those that care
instead of recreating.
