/usr/bin/lesscpy is Python 3

According to the guidelines:

https://fedoraproject.org/wiki/Packaging:Python#Executables_in_.2Fusr.2Fbin

 If the executables provide the same functionality independent of
 whether they are run on top of Python 2 or Python 3, then only the
 Python 3 version of the executable should be packaged.

I left /usr/bin/py3-lesscpy around as a symblink for backwards
compatibility. Consider removal in F30+.
