[python-win32] pywin32 build 220 adodbapi loads incorrectly on Python3.

[Vernon D. Cole]

The error I made in the manifest files for adodbapi in the former
release has been corrected, so adodbapi now installs correctly in
Python 2.  However, the conversion to Python 3 is in error.  I shall
track down that foul-up in due course.

After installing build 220 on Python3, you will need to separately
install adodbapi -- on my test bed, this worked:...

  py -3 -m pip install adodbapi
