Reflect the updated name of the package.

Seems to me as a packaging bug in python-polib. It should use python_provide
macro to handle the transition.
There is not a bug in python-polib

sh# rpm -q python2-polib
python2-polib-1.0.7-2.fc23.noarch

sh# rpm -q --provides python2-polib
python-polib = 1.0.7-2.fc23
python2-polib = 1.0.7-2.fc23

However it is a change in behaviour in dnf/yum.
You can see more details in BZ1291850 or better BZ1096506.

This a readon why "dnf builddep" will try to remove package.
(it's not downgrade from dnf point of view)

sh# dnf builddep freeipa.spec

You might try to file a dnf BZ but mine 1291850 was two tiles closed as not a
but and then closed as a duplicate of another bug.

IMHO the simplest solution would to push the patch with better explanation
in's a workaround.

LSommit message becuase it's a workaround.

Updated patch with reworded commit message.

Subject: [PATCH] spec file: rename the python-polib dependency name to
 python2-polib

Trying to install the package depending on python-polib breaks
when the system has newer (and renamed) version python2-polib.

*This patch is an workaround* for the issue described in [1].
If a renamed package's provides is equal to an older package's
name, dnf tries to install the older package.
When the newer package is in the system, this leads to a conflict.
