LC: weaken condition to lookup nested annotation

FIR LC has a different abstraction, so using the specific class name is
literally too specific to FE 1.0 LC.

We could introduce a common interface for those, but checking
`kotlinOrigin` is good enough, and thus type-checking their common
ancestor is good enough too.
