fuzz: don't err if .zig-cache/tmp doesn't exist

If we have just created cache_dir_path, then there's no `tmp` dir
there, and

    cache_dir.createFile(io, "tmp/libfuzzer.log", .{ .truncate = false })

fails.

Tested via

    $ zig version
    0.16.0
    $ zig build --zig-lib-dir ~/p/zig/lib/ --fuzz
