    libtracker-control: Remove obscure environment variables
    
    These were supposedly added for testing, but they are not used
    anywhere, nor it sounds ok to fundamentally change TrackerMinerManager
    behavior. Let's remove these.

-.B TRACKER_MINERS_DIR
-Miners that are installed should have a .desktop file in
-/usr/share/tracker/miners/, this is how tracker-control knows about
-miners which exist but may not have not been started. This environment
-variable allows the location that miner .desktop files are loaded from
-to be overridden by setting it to a new path.
-.TP
-.B TRACKER_MINERS_DIR_DISABLED
-If you don't have .desktop files for miners, you can use this
-environment variable to get status information from \fBRUNNING\fR
-processes. This doesn't give any indication for miners \fBNOT\fR
-running. This uses registered miners on DBus to know about existing
-Tracker based data miners.
