buildlet: try a bit harder to cancel slow HTTP requests

Use the new Go 1.5 mechanism to abort HTTP requests with a channel.
This is respected by the Go 1.5 http.Transport, which we always use.

This CL shouldn't be necessary (CL 14700 was the real bug), but
doesn't hurt. This still would've probably prevented most of
golang/go#12666
