Support unused dependencies

Cargo stashes unused patches into a special section of the Cargo.lock
file:

```
[[patch.unused]]
name = "uuid"
version = "1.4.1"
source = "git+https://github.com/uuid-rs/uuid#50f70278de02c106650b8d6deb325dd59b5f2a24"
```

... a section that we, currently, don't read.

Ignoring that section causes the build to fail because even if the patch
is unused, when the source is unavailable, Cargo tries to fetch it
(which, understandably, is not possible inside the sandbox).

This commit extends our logic so that we download both the "used" and
"unused" dependencies.

Closes https://github.com/nix-community/naersk/issues/308.
