Add version to binaries produced via patchGoModVendor to allow run-time provider
version validation by terraform.
This was initially introduced in 4e63119c54 (terraform: add the version component to terraform provider paths (#34497), 2018-02-06)
but broken in 3e5149a79a (terraform-providers: fix the google and google-beta providers, 2020-03-24)
for terraform-providers.google and terraform-providers.google-beta, and in 20f55a9fc0 (terraform-providers.ibm: move to update-all script, 2020-04-26)
for terraform-providers.ibm.
