Subject: [PATCH] fetcher/curl: Stop using CURLOPT_LOW_SPEED_TIME/_LIMIT

They don't play nicely currently with HTTP2 where we may
have lots of requests queued.

https://github.com/ostreedev/ostree/issues/878#issuecomment-347228854

In practice anyways I think issues here are better solved on a higher level -
e.g. apps today can use an overall timeout on pulls and if they exceed the limit
set the cancellable.

Closes: #1349
