Bug 1319441 - Skip cloud mirror when downloading logs from Taskcluster

Cloud mirror cases periodic spikes in response time (bug 1305768), so
we now use the new `x-taskcluster-skip-cache` header to skip it when
downloading eg logs/taskgraphs/...:
https://docs.taskcluster.net/reference/platform/queue/references/api#getArtifact

Since the urllib2 usage is going to be replaced with the common requests
code, and since this is hopefully a short-term workaround, hardcoding
this at point of usage should be fine.
