finetuning: use archive option for CopyFrom/ToPartition

All finetuning copy commands use -av except for the project
finetuning commands. There are many situations where the -a
option is necessary (permissions, directories, symlinks,
device nodes).

Use -av for the project finetuning partition copy commands.
