cp: show mode if target does not have S_IWUSR (PR #6696) (#6700)

Browse source 
* cp: show mode if target does not have S_IWUSR

If the target exists, and does not have the user write bit (S_IWUSR)
set, additional information should be added to the overwrite
confirmation prompt.

This should get the "i-2" test to pass. See
https://github.com/uutils/coreutils/issues/6658.

* cp: with -i, delete destination if needed
