core, shard: Make shards inherit main file's O_DIRECT flag if present
If the application opens a file with O_DIRECT, the shards' anon fds would also need to inherit the flag. Towards this, shard xl would be passing the odirect flag in the @flags parameter to the WRITEV fop. This will be used in anon fd resolution and subsequent opening by posix xl.
