libchromeos: Add standard system error support to chromeos::Error

Added methods to obtain meaningful chromeos::Error values for
standard system errors returned via errno from system APIs.

Now it is easy to provide additional context error information
when working with system APIs (such as file I/O) to report underlying
reason for failures.
