Ah, the xe-unikernel-upload opam file has a version constraint on the old 
mirage-types (and so does one of its dependencies: mbr-format).

Try

opam pin add mbr-format git://github.com/djs55/ocaml-mbr#release.0.3
opam pin add xe-unikernel-upload 
git://github.com/djs55/xe-unikernel-upload#new-mirage-interfaces

I have built these but not tested them. Let me know if they work for you and 
I’ll try to release them into upstream opam.

Cheers,
Dave
