Fixes an issue where the cname_prefix attribute isn't correctly read in region China

[by-zhou]

Fixes an issue where the cname_prefix attribute isn't correctly read China regions.

Basically as extension of a previous issue.
Elastic Beanstalk has a different domain name in China regions, which ends with eb.amazonaws.com.cn rather than the usual elasticbeanstalk.com (reference), so cname_prefix cannot be correctly read.

Changes proposed in this pull request:

• Adapt the regex expression to match cname in resource_aws_elastic_beanstalk_environment.go to be able to take cname in domain eb.amazonaws.com.cn.

Output from acceptance testing:

$ make testacc TESTARGS='-run=TestAccAWSAvailabilityZones'

Thank you for this fix @pychoude! While I cannot directly test it, it does appear to be correct in the code and according to the documentation (we appreciate the links!)

In the China (Beijing) Region, environment domains generated by Elastic Beanstalk are formatted as follows, where * denotes the custom domain: *.cn-north-1.eb.amazonaws.com.cn. For more information, see Using Custom Domains with Elastic Beanstalk in the AWS Elastic Beanstalk Developer Guide. In the China (Ningxia) Region, environment domains generated by Elastic Beanstalk are formatted as follows, where * denotes the custom domain: *.cn-northwest-1.eb.amazonaws.com.cn. In the Ningxia Region, environment domains generated by Elastic Beanstalk are formatted as follows, where * denotes the custom domain: *.cn-northwest-1.eb.amazonaws.com.cn.
