Bug#881898: mariadb-10.1: Uploads rejected by dak, blocking testing migration of mariadb-10.1 and its reverse dependencies

mariadb-10.1 (10.1.29-1) still gets uploads rejected by dak, several of
the builds are stuck in Uploaded state again.

Other builds just failed, causing mariadb-10.1 to keep blocking testing
migration of itself and its reverse dependencies.
