Ian Wienand 4f1fee6eae Fix missing libffi-devel for python-glanceclient
python-glanceclient is failing to install on rhel6 with a dependency
chain from pip as

  cryptography>=0.2.1 (from pyOpenSSL>=0.11->python-glanceclient==0.12.0.56.gb8a850c)

cryptography requires libffi-devel to build.  I'm not sure what
changed, but remove it from "testonly" so it is always installed.

However, RHEL6 includes this in the optional repo, so we enable this
repo in the fixup script.

# in a useless mess of old, rpm-packaged files and pip-installed files.

# dependency is satisfied and it will not be installed transiently.
