[Users] Default cipher in vzmigrate

Well, "vzmigrate" is a migration tool in the classical sense. So it's
fairly often used by myself or my clients when moving VPS's from an old
box at provider A to a new box at provider B.

A somewhat stronger cipher would be appreciated or at least some CLI
option that allows to override the weaker cipher.

For me it isn't a super critical issue, though. If need be there is
always the possibility to just do a simple rsync over SSH.
