Autoconf have been providing the option '--localedir' for a long time now,
so this patch removes the deprecated '--with-nls' option and makes use of
the standard '--localedir' instead.
Took opportunity to define the path in the 'config-paths.h' in the same way
the other paths are defined to be consistent, which also simplify the
compilation commands.
