Allow listening on privileged ports (below 1024) as non-root
This is done by running `setcap cap_net_bind_service=+ep` on the executable in the build stage (doing it in the runtime stage creates an extra copy of the executable that bloats the image). This only works when using the BuildKit-based builder, since the `COPY` instruction doesn't copy capabilities on the legacy builder.
