PATCH: update to a few more completions

[Oliver Kiddle <okiddle@xxxxxxxxxxx>]

This is a further update to completion of options. Updates are up to the
following versions:

  flex - 2.6.4, this was very outdated before
  gstat - FreeBSD 11.1
  sudo - 1.8.20p2
  sqlite - 3.20.0

Not too much has changed in terms of options for FreeBSD 11.1 unless we
want to somehow handle libxo stuff.

Oliver
