Please drop the obsolete golang-ed25519-dev build-depends from
obfs4proxy, it no longer seems necessary to build this package.

See attached patch, and Salsa merge request here:

https://salsa.debian.org/pkg-privacy-team/obfs4proxy/-/merge_requests/3

with pipeline build:

https://salsa.debian.org/pkg-privacy-team/obfs4proxy/-/merge_requests/3/pipelines

I'm happy to join the pkg-privacy-maintainers team to prepare and push a
team upload of this package, if anyone on the pkg-privacy-maintainers
team would approve of that?
