[FIX] mail: disable the tracking of binary fields

Tracked binary fields do not produce any message in the chatter

Steps to reproduce:
1. Install Sales and Studio
2. Open any quotation
3. Trigger Studio and add a signature field to the form
4. With debug mode enabled, edit the field (by clicking on MORE when the
   field is selected) and set the Enable Ordered Tracking to 1
5. Close Studio
6. Edit the signature and save
7. No message appears in the chatter to track the value

Solution:
Remove the `tracking` field from binary fields to prevent the user from
trying to track it

Problem:
We shouldn't track binary data in the chatter and we cannot use the
filenames
