zuul: Remove redundant airship-pegleg-tox-py36 job.

The openstack-python36-jobs template already exists; thus there
is no need for airship-pegleg-tox-py36. Since airship-pegleg-tox-py36
installs cfssl as a prerequisite for unit tests, move the install-cfssl.sh
command to tox.ini prior to unit test execution, allowing for the
airship-pegleg-tox-py36 Zuul job and its associated playbook to be
removed.
