Default to wal_sync_method=fdatasync on FreeBSD.
FreeBSD 13 gained O_DSYNC, which would normally cause wal_sync_method to
choose open_datasync as its default value. That may not be a good
choice for all systems, and performs worse than fdatasync in some
scenarios. Let's preserve the existing default behavior for now.
Like commit 576477e73c4, which did the same for Linux, back-patch to all
supported releases.
