Determine "Functional" images by association

The functional, or running, images should be determined by looking
at the functional association, not by looking at priority 0.
An image could be functional but not priority 0, this happens
after activating a new image.

Get the functional images by looking at the endpoints of
/xyz/openbmc_project/software/functional.

Resolves openbmc/openbmc#2945

Tested: Verified the correct image is functional after activation
and during other times of code updating.
