cos-customizer: Select correct provisioner arch at runtime

We ship both provisioner_amd64 and provisioner_arm64 in cos-customizer,
and we update startup.yaml to select the correct one at runtime, based
on architecture.

Since arm64 ttys have a different name in /dev, we need to template that
into the customizer systemd service.

This change does change the behavior of cos-customizer. However, an
additional change is needed for users to actually use the arm64 code
path. So the behavioral changes shouldn't be noticeable to users right
now.
