pep-0426: remove extras from Setup-Requires-Dist 

Today Setup-Requires-Dist is needed so that "python setup.py" will run at all.
Pip executes setup.py to write the requirements to a file, installs them, and
runs setup.py again to do the build/install. Not prepared to add extras to
this stage as installing a package with extras would have different results
depending on whether you were installing package[extra] from source or from a
binary.
