[Pkg-rust-maintainers] Bug#1103915: mark sqv Multi-Arch: foreign

[Peter Michael Green]

This got tied up with a more general question about debcargo,
which took a while to resolve.

I've now made an upload marking sqv as Multi-Arch: foreign,
but the "hard freeze" will hit before it's testing migration delay
finishes. I would appreciate if someone more familiar with the
package than me could do some testing and file the unblock request.
