qbittorrent: depend on nixflix.serviceDependencies (#238)

With this change, one can add some "downloads-dir.mount" (say, an NFS
mount) and ensure that qbittorrent starts after that mount.

Without this dependency a system boot runs the risk of performing such
a mount after qbittorrent starts, which invalidates the state of all
torrents (and a manual force recheck being required, lest _all_
torrents are downloaded again).

Adding all of nixflix service dependencies is perhaps a little
overzealous, but it is more uniform than adding another option.
