pybind: use syntax supported by python3.6

Fixes: f68248944815acbf5fb08ef66f36da6d5baef824
It seems the shaman CentOS8 builders, which serve as the base for container images, aren't current with the ":=" syntax. Amend to support RHEL8, whose default python is python 3.6.8.

Error example from https://shaman.ceph.com/builds/ceph/ceph-nvmeof-mon/27188b78bdbaa3c33de518b8514906de629e774a/default/388913/
