go/internal/gcimporter: call Complete on cloned Interfaces too
For "type T interface{ M() }", go/types users expect T's underlying
interface type to specify T as the receiver parameter type (#49906).
The unified importer handles this by cloning the interface to rewrite
the receiver parameters before calling SetUnderlying.
I missed in CL 425360 that these interfaces would need to have
Complete called too.
Manually tested to confirm that this actually fixes "go test -race
golang.org/x/tools/go/analysis/internal/checker" now (when both CLs
are ported to the x/tools importer).
Updates #54653.
