The uct btl should always loose to btl/sm for shared memory peers. This requires that the exclusivity be set below MCA_BTL_EXCLUSIVITY_HIGH (the exclusivity of btl/sm). The uct btl had its exclusivity set to MCA_BTL_EXCLUSIVITY_HIGH which is incorrect. This commit updates the exclusivity to the intended value.
