Pre-install libratbag

libratbag is dependency for Piper UI application that can be used
for modifying configurable mice. It also comes with ratbagctl that
allows doing this from terminal.

Considering we sometimes encounter bugs with mice that have
different polling rates, we should have a tool to allow
us discover those bugs easier with such mice.
