Add development libraries needed by Pillow

Change I8da7dd95ae24cf06dc7bdc300fcf39947a6df093 added Pillow build deps
to nodepool thick slaves.  This means that Pillow 3 will work in unit
tests.

Make the matching change to allow Pillow 3.0.0 to work under devstack.

The longer term aim is to remove temporary upper cap.
