bitbake: fetch2/s3: allow to use credentials from environment variables

Previously access to AWS S3 was expected to be preconfigured and
credentials to be stored in ~/.aws/credentials. With this change
one can use Bitbake s3 fetcher without AWS credentials stored
permanently as above, just with them exported as the following
environment variables:
 - AWS_ACCESS_KEY_ID,
 - AWS_SECRET_ACCESS_KEY.
 - AWS_DEFAULT_REGION.
