feat: add inputDrvs to the JSON

Browse source 
Currently, not a lot of things expose inputDrvs (except
`show-derivation`), which is a showstopper whenever you want to compute
popularity ranking based on the dependency relation.

Having `inputsDrvs` in the reply enable downstream users to perform such
computations in an efficient way.
