binutils/glibc-testsuite: inherit nopackages to fix world builds

These recipes don't need to generate packages but did contain the packaging tasks which
would be triggered by a world build. They showed warnings or errors. Simplest fix
is to remove the unneeded tasks with the nopackages class.

Also don't attempt stash_locales task
