iconv: init (portable attribute for iconv(1))

Browse Source 
This obsoletes this pattern:

     if stdenv.isDarwin then libiconv
     else buildPackages.stdenv.cc.libc

Which was not portable, as some platforms don't have libiconv in libc,
and some of those that do still don't have iconv(1) in their libc
package.
