Commit 00fcc832d598 ("Update Python package requirements") added a
PEP 508 environment marker to install pywin32 on Windows systems.

This requires a new setuptools version (>= 20.5), but (at least)
RHEL/CentOS7 and Debian Jessie are using an older version of
setuptools and so python extension failed to build.

This commit adds "extras_require" instead of the PEP 508 environment
markers in order to have the conditional dependency of pywin32, but by
remaining compatible with the old setuptools versions.
