[PATCH rdma-core 1/5] cbuild: Make pyverbs build with epel

[Jason Gunthorpe <jgg@xxxxxxxx>]

From: Jason Gunthorpe <jgg@xxxxxxxxxxxx>

For some reason cmake3 installs python3.6, but EPEL only has cython
built for python3.4. Convice the python3 link to be python3.4 so cmake
finds it without hassles.
