migration: T5413: re-sequence interfaces migration scripts
PR https://github.com/vyos/vyos-1x/pull/2540 backported a migration script from
current to the equuleus LTS branch. As migration scripts are executed in order
to adjust the CLI for necessary improvements in future LTS releases we need to
change the versioning of the migration files to match the new "base" version
from the previous LTS release.
In theory this could break very ancient 1.4 rolling releases (from the early
days of the OSPF refactoring) - but those versions are considered very much
unstable.
Now this is the last chance to sync up the migration scripts before the 1.4 LTS
release.
