Bug#909086: opam: Missing dependency on bubblewrap

[Ralf Jung <post@ralfj.de>]

Package: opam
Version: 2.0.0-3
Severity: normal

Dear Maintainer,

I installed opam with "--no-install-recommends", and now creating an opam root fails saying

[ERROR] Missing dependencies -- the following commands are required for opam to operate:
  - bwrap: Sandboxing tool bwrap was not found. You should install 'bubblewrap'. See http://opam.ocaml.org/doc/2.0/FAQ.html#Why-opam-asks-me-to-install-bwrap.

Seems like opam should "Depends: bubblewrap".

Kind regards,
Ralf
