migrations: fix _depends references left stale by the border chain rename

be8a1cf renamed the 5 border migration files but only staged the git-mv
itself; the _depends edits pointing each file at its new predecessor name
(0066-init-border chained after 0065-registration-client-auto-provision,
and 0067-0070 each bumped one) were made in the working tree afterwards
and never got committed. Left as-is, every _depends referenced a filename
that no longer existed post-rename, so the migration graph was still
broken (just differently). This completes what be8a1cf's message already
claimed to do.
