Arseny Maslennikov 6bfa4a28aa /usr/lib/rpm/functions: split away to rpmb-functions 
In an environment created by `hsh --initroot-only`:

The `scripts/functions` file is provided from the rpm project in real
installations. Let's ensure scripts in this package use the functions
file from this package.
