Fix gensim build (docs & pyemd issues) (#2318)

* disable-pyemd

* revert pyemd to setup.py (it still works on linux)

* extend 'catch' on import

* correct test skipping

* fix flake8

* fix docs building

* correct skipping if pyemd not available

* fix typo

* upd

* pin sphinx

* revert sphinx pin

* disable -W for sphinx (REVERT ME), issue not reproduced locally, only here

* more verbosity

* MOAR verbosity

* try to use different path

* build binaries before docs

* pin previous version of programoutput (avoid bug from 0.13)

* revert Makefile

* fix

* disable programoutput sphinx plugin

* revert pinning

* one more attempt

* cleanup

* cleanup[2]

* fix
