Reduce size of CoreOS ramdisk

Browse Source 
By disabling pip cache, we're able to reduce the size of generated
docker image by 10%. The resulting ramdisk size goes from 229MB to
218MB.

It is possible to decrease the size even further by combining all the
RUN instructions into one but it doesn't provide a substantial gain and
it harms readability.
