bts: More complete AGCH / IMM.ASS testing
The existing test simply sent 1000 messages via RSL without checking
what actually arrived on the radio interface, or without
expecting/counting any RSL DELETE IND.
Let's fix this by introducing test sending IMM.ASS at three different
rates, with related expectations in terms of nubmer of IMM.ASS arriving
on Um vs. RSL DELETE IND arriving at BSC.
