    Double the file descriptor limit for openFile008
    
    I have get test failures on `openFile008` with
    `openFile: resource exhausted (Too many open files)` when running
    inside `./validate`, but not when I run the test individually.
    I suspect that's because with `./validate` parallelism of 33 threads
    I go just above the `1024` file descriptor limit.
    This is probably related to the recent change:
    `58f0086b70f2: Testsuite: open/close stdin/stdout/stderr explicitly`
    but I haven't looked deep enough to understand exactly how.
    I think bumping this is harmless, but I don't really know why it's
    necessary at all.
    
    Test Plan: ./validate
