I have an error when building a functionbeat lambda to ship other lambdas logs to elastic cloud.  
The reason is that the name is too long. According to the documentation should be ~20 chars long, but in this case is 16 chars long and it fails.

```auto
...
functionbeat.provider.aws.functions:
  - name: logmyproject-devstag
...

```

I tracked down to this line of code

> <https://github.com/elastic/beats/blob/master/x-pack/functionbeat/manager/aws/template_builder.go#L267>

I exported the function using 7.12.1 I see that the role name

```auto
"RoleName": "functionbeat-lambda-logmyproject-devstag-eyAiUmVmIjogIkFXUzo6UmVnaW9uIiB9"

```

The issue I detected is that `eyAiUmVmIjogIkFXUzo6UmVnaW9uIiB9` is the base64 of  
`{ "Ref": "AWS::Region" }`

How can I fix this?
