bad relative imports are introduced

[pavlix]

Modernize introduces bad syntax when dealing with imports from local packages.

Original code:

import ssl.SSLCommon

Modernized code containing syntax error:

from . import ssl.SSLCommon

Probably desired code:

from .ssl import SSLCommon as ssl_SSLCommon

[ncoghlan]

The local translation that will keep name resolution consistent:

from .ssl import SSLCommon # Ensure import
from . import ssl # Bind top level name
