If plugins are specified in a call to `terraform.withPlugins`, the
standard override functions do not act on the wrapper derivation that
a user sees but on the underlying Terraform derivation.
Due to this, overriding attributes does nothing as they are not passed
through to the "outer" wrapper derivation.
This change fixes this for at least passthru attributes, but other
applications of `.overrideAttrs` (and potentially of the other
overrides) will do nothing (except compute a bit internally).
This fixes#158620 at least partially.
- add flag to skip building updated providers
- have the github action skip building providers so we don't need to handle build failures in the script
- remove outdated `vendor` flag, all providers use `buildGoModule`
Terraform needs the plugin directory to not be a tree of symlinks,
because it uses https://pkg.go.dev/path/filepath#Walk under the hood.
This restores some of the work that had been undone in

`--provisioner qemu` was also tested. Note you need to have
`_out/{initramfs-$arch.xz,vmlinuz-$arch}` available, as documented in
their [docs](https://www.talos.dev/docs/v0.14/local-platforms/qemu/#install-talos-kernel-and-initramfs)
