Revert #847 ?

[cgohlke]

Please consider reverting #847 (FIX python-lz4 version comparison)

Importing pkg_resources is known to be excruciatingly slow. See pypa/setuptools#510

On my Windows workstation, import pkg_resources takes more than 3 s.

Also, I can't reproduce that The python-lz4 package has its version string prefixed with "v":

>>> import lz4
>>> lz4.__version__
'2.2.1'
>>> from distutils.version import LooseVersion
>>> LooseVersion(lz4.__version__)
LooseVersion ('2.2.1')

Indeed I was not aware of this. We need to revert but also add a special handling of the "v" prefix in the version number of python-lz4.

@cgohlke joblib 0.14.1 is out with a fix for this regression. Thanks for the report.
