Move url_request_mock_http_job to net/test/url_request/

This CL is a part of the effort to move mock URLRequestJob files
from content/test/net to net/test/url_request/. The reason for this
refactoring is that Cronet will need to use these classes for testing,
so it will be nice if they can be in net/test, as the dependency can
work out nicely.
