Activation: support updating PSU from stored image

The previous code assume the image to update is from IMG_DIR.
Now it needs to update PSU from pre-built or stored images.

This commit adds the support, by constructing the systemd unit based on
Activation's Path property instead of IMG_DIR.

Tested: Verify on Witherspoon that it is able to activate a stored
        image.
