backup: Drop obsolete backup scripts

These custom scripts are not used for several years now and they were
replaced by more systematic backup system including all our servers.

backup/README

-Here are various scripts that help backing up the databases and maintaining
-them.
-
-Currenty, we have these:
-
-backup-turris::
-  Backs up the main turris database from db.turris.cz to archive.turris.cz, in
-  a strongly encrypted form. This should be run from cron.
-
-store-backup::
-  A forced command for SSH, on the receiving side. This will accept the data
-  and store it into a file. This is configured with a key in .ssh/authorized_keys.
-
-purge-backups::
-  This is run on archive.turris.cz, to clean up old database backups.
