Optimize FileChannelJournalSegmentWriter.truncate()

FileChannelJournalSegmentWriter.truncate() is inefficient in that it
zeroes-out its memory buffer and then writes it completely out.

This patch aligns it with what MappedJournalSegmentWriter does, which is
just zeroing out the entry header -- reducing both IO and CPU overheads.
