prowler: fix IAM role detection and curl error

Browse Source 
Related to https://github.com/toniblyx/prowler/pull/200

If the ec2 instance is not attached to an IAM role, the `curl -s -m 1
http://169.254.169.254/latest/meta-data/iam/security-credentials` will
return a 404 page instead of null, INSTANCE_PROFILE will always be true
and result to curl error when trying to use default cli profile:

    curl: option -: is unknown
    curl: try 'curl --help' or 'curl --manual' for more information
