Fix fetcher::QuickInstallstats report sending (#918)

Fixed https://github.com/cargo-bins/cargo-quickinstall/issues/195

 - Fix `fetchers::QuickInstall`: Stop sending stats for `universal-apple-darwin`
   since quickinstall only supports targets officially supports by rust.
 - Only send stats report to quickinstall if the `Fetcher::find` is `.await`ed on
   
   This prevents stats report to be sent for cases where the `QuickInstall` fetcher
   is actually unused, e.g. resolved to `GhCrateMeta` or other `QuickInstall` fetcher
   with different target.
   
   This also reduces amount of http requests created in background.
