Enabled parallel direct IO writes for passthrough examples

All these passthrough examples don't need writes to be serialized.

Actually, most file systems probably handle non serialized parallel
direct writes - the FOPEN_PARALLEL_DIRECT_WRITES flag is just
to avoid a regression for those file system that rely on serialized
DIO writes in fuse kernel. Passthrough file system forward the IO
to another file system, which actually handles that internally -
serialized in fuser kernel is not needed.
