The tracker-miners module is only needed for:
  * the org.freedesktop.Tracker1.Miner.Files.service file and symlink
    that are used by tracker_miner_manager_get_status
  * the org.freedesktop.Tracker.Miner.Files schema that's used to get
    any custom locations configured through Settings -> Search

The only ELF binaries are in /lib/tracker-miners-2.0. Since those are
not global, and there are simply no other binaries, it ought to be
safe to remove them.
