doc: fix info on cp --preserve=all, which does _not_ give xattr warnings

The info docs have been inaccurate since 2009-04-17, commit 941bd482,
"mv: ignore xattr-preservation failure when not supported by filesystem"
* doc/coreutils.texi (cp invocation): Say that cp --preserve=all
does _not_ output errors when failing to copy xattrs.
