Install example psu-update@.service

The repo needs an example psu-update@.service, it was expected to be
installed by a bitbake recipe, but during the recipe review it turns
out that the repo is better to install a default one and it could be
overriden by a bbappend.

Move the psu-update@.service from vendor-example to services directory
and install it.

Tested: Verify the service is installed.
