Include the name in the JSON for derivations

Browse source 
This is non-breaking change in the to-JSON direction. This *is* a
breaking change in the from-JSON direction, but we don't care, as that
is brand new in this PR.

`nix show-derivation --help` currently has the sole public documentation
of this format, it is updated accordingly.

derivations, and whose values are a JSON object with the following
fields:
* `name`: The name of the derivation. This is used when calculating the
store paths of the derivation's outputs.
* `outputs`: Information about the output paths of the
derivation. This is a JSON object with one member per output, where
the key is the output name and the value is a JSON object with these
