Fix DefaultComponentInstaller::FinishRegistration and group policy.

The code in DefaultComponentInstaller::FinishRegistration is not updating
the value of CrxComponent::supports_group_policy_enable_component_updates
with the value provided by the specific installer traits.

Therefore, the components using the DefaultComponentInstaller for their
installer ignore the group policy settings for controlling the update behavior.

I verified that the group policies are effective by inspecting the update check.
