gbmap: Renamed gbmap_scan_thresh -> gbmap_rebuild_thresh

Browse Source 
I think a good rule of thumb is if you refer to some variable/config/
field with a different name in comments/writing/etc more often than not,
you should just rename the variable/config/field to match.

So yeah, gbmap_rebuild_thresh controls when the gbmap is rebuilt.

Also touched up the doc comment a bit.
