resource/codebuild: Increase timeout for creation retry (IAM)

[radeksimko]

This is to address the following test failure:

=== RUN   TestAccAWSCodeBuildProject_basic
--- FAIL: TestAccAWSCodeBuildProject_basic (15.12s)
    testing.go:428: Step 0 error: Error applying: 1 error(s) occurred:
        
        * aws_codebuild_project.foo: 1 error(s) occurred:
        
        * aws_codebuild_project.foo: [ERROR] Error updating CodeBuild project (arn:aws:codebuild:us-west-2:*******:project/test-project-6kum6jemzb): InvalidInputException: CodeBuild is not authorized to perform: sts:AssumeRole on arn:aws:iam::*******:role/codebuild-role-6kum6jemzb
            status code: 400, request id: 4f535692-5320-11e7-8006-2d816cc1e349

I'm aware this may uncover some other errors, but I think it's better to scope down the retry to specific error codes rather than blindly retry on any error and delay displaying genuine user errors.
