[coreutils] stat and SELinux context

[Eric Blake]

In working on the birthtime stat support, I noticed that we documented 
that -Z has been removed, on the grounds that you can get at it with 
--format=%C (although NEWS didn't mention the replacement).

Would it make sense to patch the default stat output (with no --format) 
to automatically supply the %C line that Fedora's stat -Z has already 
been patched to provide?  That is, if coreutils is compiled with SELinux 
support, I see no reason why the context information should not be part 
of the default output.  That way, on Fedora, where you now use 'stat -Z' 
because of a distro-specific patch to override -Z being a no-op, you 
would in the future ALWAYS get %C output without having to use -Z.

Besides, now's the perfect time to change the default output to include 
%C where available, given that we're already changing it to add %w 
birthtime ;)
