Subject: [PATCH] test: wire lib/memio/memiotest.ww into make test

memiotest.ww existed and passed under `out/bin/ww run` but no
test/wcc/*.c ran it under `make test`. New 980_memio_run runs it
and propagates exit; matches the 998_bufio_run pattern.

980-989 is the new sub-band for stdlib-run integration tests.
