build: use add_dist_script for vendoring

Our workaround for getting meson and cargo working together
included a separate 'release' target that replaced
'ninja dist' so that we could vendor dependencies.

Now we use meson's add_dist_script to vendor the
dependencies as part of 'ninja dist', so we no longer need
the 'release' target.
