PoC: build offline support

Since commit 1d433f6 ("feat(db): confirm list of all packages that will be removed") packages need confirmation by default when being dropped from the db. If we make it to the DB drop phase the package already is pushed to the AUR, so it is safe to remove from the database and not removing it would create a somewhat broken state, so we assume that the package should unconditionally be removed from the db.
