Avery Pennarun 806de4ac94 portlist: fix "readdirent: no such file or directory" errors on Linux.

This could happen when a process disappeared while we were reading its
file descriptor list.

I was able to replicate the problem by running this in another
terminal:

    while :; do for i in $(seq 10); do
      /bin/true & done >&/dev/null; wait >&/dev/null;
    done

And then running the portlist tests thousands of times.

Fixes #339.
