[Pkg-rust-maintainers] Bug#981256: cargo: drop unused cmake build dependency

[Helmut Grohne]

Source: cargo
Version: 0.47.0-3
Tags: patch
User: helmutg at debian.org
Usertags: rebootstrap

cargo participates in dependency loops relevant to architecture
bootstrap. Rather than looking into such a difficult problem, I looked
into easly droppable dependencies and found that cargo no longer uses
cmake in anyway. Please consider just dropping it. I'm attaching a patch
for your convenience.
