[lldb][test] Remove vendored packages unittest2 and progress (#82670)

Browse Source 
The `unittest2` package is unused since
5b386158aacac4b41126983a5379d36ed413d0ea.

The `progress` package was only used internally by `unittest2`, so it
can be deleted as well.

unittest2
unittest2 is a backport of the new features added to the unittest testing
framework in Python 2.7. It is tested to run on Python 2.4 - 2.6.
To use unittest2 instead of unittest simply replace ``import unittest`` with
``import unittest2``.
