Test:: modules are build-time dependencies, but are listed as run-time dependencies

[chrisnovakovic]

In CGI-4.04, Test::Deep and Test::More are listed in META.json as run-time dependencies:

   "prereqs" : {
      "build" : {
         "requires" : {}
      },
      "configure" : {
         "requires" : {}
      },
      "runtime" : {
         "requires" : {
            "File::Spec" : "0.82",
            "Test::Deep" : "0.11",
            "Test::More" : "0.98",
            "if" : "0",
            "perl" : "5.008001"
         }
      }
   },

In fact, these modules are only ever used in the test scripts (Test::Deep in t/request.t, Test::More pretty much everywhere) and can therefore be moved to the "build" section of META.json.
