Allow extensions to be run when Talos platform is container

[Mattias Cockburn]

Feature Request

Description

Currently no extensions work when Talos is running inside a container, as implemented in

talos/internal/app/machined/pkg/controllers/runtime/extension_service_config_files.go

Line 59 in 7b37e5b

 if ctrl.V1Alpha1Mode == v1alpha1runtime.ModeContainer { 

We'd like to be able to test extensions like our custom code in a containerized Talos but are currently forced to run a custom fork with the conditional removed for this to work.

Our use case is a bit different but it would be great if at least some of the extensions could be used in containers (e.g. iscsi-tools).
