Add very hacky script to generate Perl packages

Given the name of Perl module, this script will download the package
containing the module from CPAN, determine its dependencies, and print
a Nix expression suitable for inclusion in perl-packages.nix on
stdout.

Example:

$ ./maintainers/scripts/generate-cpan-package DBIx::Class
  DBIxClass = buildPerlPackage {
    name = "DBIx-Class-0.08205";
    src = fetchurl {
      url = mirror://cpan/authors/id/F/FR/FREW/DBIx-Class-0.08205.tar.gz;
      sha256 = "16iyrfvwf4y94wxpwlla131grdf10z4xx9q9s6jsi39ycaxdaj6l";
    };
    buildInputs = [ DBDSQLite PackageStash TestException TestWarn ];
    propagatedBuildInputs = [ ClassAccessorGrouped ClassC3Componentised ClassInspector ConfigAny ContextPreserve DataCompare DataDumperConcise DataPage DBI DevelGlobalDestruction HashMerge ModuleFind Moo MROCompat namespaceclean PathClass ScopeGuard SQLAbstract SubName TryTiny ];
    meta = {
      homepage = http://www.dbix-class.org/;
      description = "Extensible and flexible object <-> relational mapper.";
      license = "perl";
    };
  };

anymore.
ledger-2.6.3: update location of the source code tarball

The source code tarball we used to rely on has disappeared.
ledger-2.6.3: update the location of the source code tarball some more

I found the original tarball at a different URL. This one doesn't
require Autoconf et al to compile.
