Centralize options to build Clear Containers components

[gorozco1]

We already have https://github.com/01org/cc-oci-runtime/blob/master/installation/installation-setup.sh which specifies the set of options to use to build qemu-lite. Ideally, we'd have a single source for these options as both debian.rules and qemu-lite.spec are also specifying these values. I don't think it's important for other packages (including the runtime), but for qemu-lite, we are much more likely to want to make changes and having to update the option(s) in 3 places will be error prone and tedious.

The same rule should apply to the options to build cc-oci-runtime and probably the kernel.
