bug(cp): like gnu/cp, don't show any message when --no-clobber is used

Browse source 
Simple example:
touch bar
rm -rf /tmp/foo
mkdir -p /tmp/foo
cp -pnL -v bar /tmp/foo
echo $?
cp -pnL -v bar /tmp/foo
echo $?

rm -rf /tmp/foo
mkdir -p /tmp/foo
./target/debug/coreutils cp -pnL -v bar /tmp/foo
echo $?
./target/debug/coreutils cp -pnL bar /tmp/foo
echo $?
