Merge #19614: util: use HAVE_FDATASYNC to determine fdatasync() use

1d8338d6b7 util: use HAVE_FDATASYNC to determine fdatasync() use (fanquake)

Pull request description:

  Rather than just using on Linux and NetBSD, use `fdatasync()` based
  on whether it's available. i.e `fdatasync` is available in newer versions of FreeBSD.

  This also aligns more closely with what is being done in leveldb.

  Was pointed out by Luke in #19430.
