mariadb: Fixes incremental backup failure when full not created today
backup_full() saves the history name in $BACKUP_DIR/last_full_date.
backup_incremental() attempts to read from $BACKUP_DIR/last_full_date
into $LAST_FULL_DATE. After the read attempt; if $LAST_FULL_DATE is zero
length then $(date +%d-%m-%Y) is used.
