[FIX] Fixed missing package in Odoo 8.0 base image
This fixes an issue reported by @luistorresm here where the fonts were showing different in runbot and dev instances.
The lack of the installed package doesn't show any error, just seems to install an additional font / font-family.
@moylop260 I think we should move all packages actually required by Odoo to the base image and install those required to test and dev only in the shippable image, because we end with different environments. IMHO we should have at least the same base for prod, dev and test to avoid this issues in the future. What do you think?
