use local cargo dependencies

We should not try to build with deps from the vendor directory locally.
This will force me to run make vendor manually if I pull in new deps.

When distros want to build with bundlwd deps they should a) download
the linked vendor tarball which we should provide for the releases and
b) create the cargo config since to let cargo use the vendor dir.
```
tar xvf %{SOURCE1}
mkdir -p .cargo

cat >.cargo/config << EOF
[source.crates-io]
replace-with = "vendored-sources"

[source.vendored-sources]
directory = "vendor"
EOF
```

 The Fedora package builds Aardvark-dns using a compressed tarball of the vendored
 libraries that is attached to each upstream release.
+You can download them with the following:
+
+`https://github.com/containers/netavark/releases/download/v{version}/aardvark-dns-v{version}.tar.gz`
+
+And then create a cargo config file to point it to the vendor dir:
+```
+tar xvf %{SOURCE}
+mkdir -p .cargo
+cat >.cargo/config << EOF
+[source.crates-io]
+replace-with = "vendored-sources"
+
+[source.vendored-sources]
+directory = "vendor"
+EOF
+```
 
 The `aardvark-dns` binary is installed to `/usr/libexec/podman/aardvark-dns`.
