Replace wildcard imports in top-level git module

- Use explicit imports instead of * imports.
- Remove now-unneeded linter suppressions.
- Alphabetize inside the try-block, though this will be undone.

This currently fails to import due to a cyclic import error, so the
third change, alphabetizing the imports, will have to be undone (at
least in the absence of other changes). It is not merely that they
should not be reordered in a way that makes them cross into or out
of the try-block, but that within the try block not all orders will
work.

There will be more to do for backward compatibility, but the
modattrs.py script, which imports the top-level git module, cannot
be run until the cyclic import problem is fixed.
