add a filelist for cabal sdist

I hate hard-coded 40 kilobyte lone file lists, and just once would like to
see a build system that does not assume it's a good idea to have a file
list, or a hardcoded file list, or a file list that can only be generated
with a crippled form of globs. But not today, thank you cabal.
