Issue MESOS-5944: Remove `O_SYNC` from StatusUpdateManager logs
Currently the {{StatusUpdateManager}} uses {{O_SYNC}} to flush status updates to disk. We don't need to use {{O_SYNC}} because we only read this file if the host did not crash. {{os::write}} success implies the kernel will have flushed our data to the page cache. This is sufficient for the recovery scenarios we use this data for.
