return xcodebuild error message to client

[KazuCocoa]

Returns xcodebuild error in error message to client. The message is in message and stacktrace in W3C error format.

Users can see WDA build error as client side message. I hope this helps users to take a look signing issue (for example).

• in Ruby client (Below is a combination of an error message and stacktrace)
