Test default pkg-url for GitLab and BitBucket (rust-lang#322)

* Test default `pkt-url` for GitLab and BitBucket
* Fail if `cargo-build` is called when testing GitLab/BitBucket
* Fix use of `remote_exists` in `GhCrateMeta::launch_baseline_find_tasks`
   
   If `Method::HEAD` fails, try `Method::GET` since some servers reject
   `Method::HEAD`, e.g. bbuseruploads.s3.amazonaws.com
