docker: remove dependency on explicit go-cross version
docker: remove dependency on explicit go-cross version

go-cross-1.3 is old, and doesn't link properly with the latest 2.26
binutils.

To get things building again, and to start the docker uprev, we simply
depend on go-cross and line docker up with the rest of the go users.
