native.bbclass: Properly define directories

For most users this commit will have no effect. But if you come across the idea of giving
different names for paths, you'll get some troubles.

When a recipe inherit native, properly define bindir, sbindir, includedir, sysconfdir, datadir
(using xxxdir_native definitions from meta/conf/bitbake.conf).

For example, edit "${BASE_WORKDIR}/${MULTIMACH_TARGET_SYS}/quilt-native/temp/log.do_configure"
and see what are the arguments given by oe_runconf.

Notice that ${docdir}, ${mandir}, ${infodir}, ${localstatedir} have no associated _native definition.
