Produced binary package for Oracular is Python2 only

[Skia]

The `python3-amqplib/1.0.2-4` package build is broken on Oracular: it's missing a magical 2to3 step.

Using it leads to that kind of traceback:
```
  File "/usr/lib/python3/dist-packages/amqplib/client_0_8/connection.py", line 96, in __init__
    login_response.write_table({'LOGIN': userid, 'PASSWORD': password})
  File "/usr/lib/python3/dist-packages/amqplib/client_0_8/serialization.py", line 370, in write_table
    table_data.write_shortstr(k)
  File "/usr/lib/python3/dist-packages/amqplib/client_0_8/serialization.py", line 338, in write_shortstr
    if isinstance(s, unicode):
                     ^^^^^^^
NameError: name 'unicode' is not defined
```

A quick test to check the Python 3 compatibility is the following:

$ grep 'isinstance.*unicode' /usr/lib/python3/dist-packages/amqplib/client_0_8/serialization.py
        if isinstance(s, unicode):
        if isinstance(s, unicode):
                if isinstance(v, unicode):

This should not return any result, but on Oracular I get the output above. This is not happening on Noble and before.

I did not investigate much further, but a local manual build also produces a broken binary package. From what I've seen in the launchpad build logs, previous version were installing python3-lib2to3 during the build, and this is not the case anymore.

A quick workaround for anyone affected is to run the following:
sudo 2to3 -w /usr/lib/python3/dist-packages/amqplib/client_0_8/*

Discussed with the Debian side, and this package will likely get dropped. Could somebody please set that as WontFix and update the tags accordingly?
