copy: be more defensive/restrictive with posix_fadvise

* src/copy-file-data.c (copy_file_data): Only give the
POSIX_FADV_SEQUENTIAL hint when we _know_ we'll definitely
use a read/write loop to copy the data.  Also only apply
the hint to the whole file, as we've seen OpenZFS at least
special case that.
(sparse_copy): Update stale comment.
