doc: suggest dd "sync" flag to maximize "nocache" effectiveness
doc/coreutils.texi (dd invocation): Add oflag=sync to the streaming
example. Also reference the "direct" flag. Mention this is only
a request to the system.
* src/dd.c (usage): Mention the "sync" flag along with "nocache".
Also mention that it's only a request to drop the cache.
* THANKS.in: Add reporter Francois Rigault.
