pkg/lists: uncrustify Makefile

The problem with the changed piece of code is that it would - both call cp(1) multiple times if multiple *_LIST variables were non-empty (which is usually the case), and - try to evaluate stdout of the called commands as a shell script (which would be empty unless someone passed e.g. -v to that cp(1) but it's crazy to rely on things like this). So the functions should prepare arguments for a single copy command that is predictable and could be made verbose. Ouch.
