[Python] Pyarrow is raising deprecation warning about filesystems on import

[asfimport]

This happens on import (when setting the warning to be visisble), so even when the user doesn't use the deprecated filesystems:

In [1]: import warnings

In [2]: warnings.simplefilter("always")

In [3]: import pyarrow
/home/joris/scipy/repos/arrow/python/pyarrow/filesystem.py:255: DeprecationWarning: pyarrow.filesystem.LocalFileSystem is deprecated as of 2.0.0, please use pyarrow.fs.LocalFileSystem instead.
  cls._instance = LocalFileSystem()

I forgot to add a filter in the construction of the LocalFileSystem ..
