package.py creates AWS::Serverless::Function Environment Variables property incorrectly

[earchibald-lv]

AWS::Serverless::Function implements environment variables as

{ "Properties": {
  "Environment": {
    "Variables": { ... } } }

(see https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-lambda-function-environment.html)

However, package.py is defining the structure as:

{"Properties: {
  "EnvironmentVariables": {
    "Variables": { ... } } }

Thanks for reporting it. I'll get this fixed.
