feat(download): Filter out country-specific SQLite DBs

The country-specific SQLite DBs currently available for download from
https://dist.whosonfirst.org have a few integrity issues. This causes
problems in Pelias such as addresses in NYC or Berlin not having proper
admin information.

The planet-wide SQLite DB, while a little out of date, is overall more
valid.

While in the long term we probably want to utilize the country-specific
DBs, for now it makes sense to filter them out.
