coreutils: revert upstream commit causing havoc with ls output

A recent commit causes ls to have the following behaviour:

   meta-overc:~$ mkdir abc
   meta-overc:~$ cd abc
   meta-overc:~/abc$ touch  aaaa bbbb 'filename with spaces'
   meta-overc:~/abc$ ls
   aaaa  bbbb  'filename with spaces'
   meta-overc:~/abc$

Note the appearance of quotation marks.  This new behaviour was
introduced as "opt-out" and not "opt-in", and further, the opt-out
suggestion causes other breakage.  More details can be found here:

  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=813164

Several large distros are reverting the change, for practical
considerations as per what can be seen above for Debian.

Here we do the same; I've marked the patch as upstream submitted
since there have been enough people vocally annoyed by this change
that it seems implausible that the coreutils team is unaware of it.

Hopefully this change here is just temporary and the coreutils team
will put the default back to the old way it was based on feedback
similar to what is recorded in the above Debian bug.
