Description: With the package `python-pyarrow` installed, I get the following error when I try to import pandas:

import pandas as pd
AttributeError Traceback (most recent call last)
<ipython-input-1-7dd3504c366f> in <module>
----> 1 import pandas as pd

/usr/lib/python3.9/site-packages/pandas/ in <module>
21 # numpy compat
---> 22 from pandas.compat import (
23 np_version_under1p18 as _np_version_under1p18,
24 is_numpy_dev as _is_numpy_dev,

/usr/lib/python3.9/site-packages/pandas/compat/ in <module>
21 np_version_under1p20,
22 )
---> 23 from pandas.compat.pyarrow import (
24 pa_version_under1p0,
25 pa_version_under2p0,

/usr/lib/python3.9/site-packages/pandas/compat/ in <module>
6 import pyarrow as pa
----> 8 _pa_version = pa.__version__
9 _palv = Version(_pa_version)
10 pa_version_under1p0 = _palv < Version("1.0.0")

AttributeError: module 'pyarrow' has no attribute '__version__'

Without having `python-pyarrow` installed, it works fine.

Additional info:
* python-pandas version 1.3.0-1
* python-pyarrow version 3.0.0-1

Steps to reproduce: Install both, `python-pandas` and `python-pyarrow` and try to import pandas in a python environment.

python-pyarrow does not supply any .py files specifically need in this case is which provides __version__.
The attached diff adds the pure python files but also introduces some test failures.
