Cleanup the RetryTimeoutCallback().

When canceling a request or destroying the LibcurlHttpFetcher, a
RetryTimeoutCallback callback could be leaked if the fetcher was
waiting on a network retry.

This patch keeps track of the retry callback and cancels it on CleanUp,
making sure the callback is not leaked.

Bug: 34178297
Test: Added unittest to trigger this case.
