lib: extract NETWORK_ADDRESS and NETWORK_PREFIX as macros

Browse Source 
The 169.254.0.0/16 network specification (for the appliance) is currently
duplicated between the direct backend and the libvirt backend. In a
subsequent patch, we're going to need the network specification in yet
another spot; extract it now to the NETWORK_ADDRESS and NETWORK_PREFIX
macros (simply as strings).
