Subject: doc: group dd conv= options that are actually flags

* src/dd.c (usage): Move 'sync' up with other data transformation
options.  Having it alongside 'fsync' and 'fdatasync' is
particularly confusing.  Also the double line description of
the 'sync' option, serves as a visual break from the "flag"
type options that follow.
* doc/coreutils.texi (dd invocation):  Apply the same grouping
as above, by splitting the "conv=" table in two.
