Upload lambda to region specific buckets

[lox]

Seems like lambda's need to be from a bucket in the same region, so this uploads to multiple regions.

@toolmantim this is currently blocked on needing the latest version of awscli on the build machine.

I just updated it:

aws-cli/1.11.35 Python/2.7.6 Linux/3.13.0-77-generic botocore/1.4.92

The error in the build is now:

fatal error: An error occurred (InvalidRequest) when calling the ListObjects operation: You are attempting to operate on a bucket in a region that requires Signature Version 4.  You can fix this issue by explicitly providing the correct region location using the --region argument, the AWS_DEFAULT_REGION environment variable, or the region variable in the AWS CLI configuration file.  You can get the bucket's location by running "aws s3api get-bucket-location --bucket BUCKET".
