libalpm: Force update when database is marked as corrupted.
When a database and its signature is updated non-atomically on a server,
there is a window where a user may update the database but grab the old
signature. The database is marked as invalid by libalpm, which can be
fixed by forcing a refresh (assuming the server has caught up and the
user realizes what has happened) or with a future update of the repo.
Work around this by forcing a repository refresh whenever a database is
invalid.
