packages/fff: move config scripts to fff-layer3-config

configuregateway and it's gateway.d files represent a specific
functionality that other packages depend on. Thus, it is put into
a package of its own so dependencies can be expressed more properly.

While at, use the chance to get rid of the ambiguous term "gateway"
and rename the script to configure-layer3 and the folders to layer3.d.
