Add a way to get all the outputs of a derivation with their label

Browse source 
Generalize `queryDerivationOutputNames` and `queryDerivationOutputs` by
adding a `queryDerivationOutputMap` that returns the map
`outputName=>outputPath`

(not that this is not equivalent to merging the results of
`queryDerivationOutputs` and `queryDerivationOutputNames` as sets don't
preserve the order, so we would end up with an incorrect mapping).

squash! Add a way to get all the outputs of a derivation with their label

Rename StorePathMap to OutputPathMap
