coreutils: fixing an cp-, mv- and install-error

This udpate fixes the following issue for coreutils:
- bnc#788459: cp could read from freed memory and could even make corrupt copies. This could happen with a very fragmented and sparse input-file, on GNU/Linux file-systems supporting fiemap extent scanning. This bug also affects mv when it resorts to copying, and install
