serialise versus benchmark fails to parse internal cabal libraries

[FinleyMcIlwaine]

Cabal 2.0 introduced internal libraries which are specified by library fields accompanied by a name. The benchmark errors when it sees such a name:

cborg/serialise/bench/versus/Macro/Load.hs

Line 2179 in c31a1c0

syntaxError line_no "'library' expects no argument"

The following is the log of the failure from cabal bench:
