Fix background_thread creation for the oversize_arena.

Browse source 
Bypassing background thread creation for the oversize_arena used to be an
optimization since that arena had eager purging.  However #2466 changed the
purging policy for the oversize_arena -- specifically it switched to the default
decay time when background_thread is enabled.

This issue is noticable when the number of arenas is low: whenever the total #
of arenas is <= 4 (which is the default max # of background threads), in which
case the purging will be stalled since no background thread is created for the
oversize_arena.
