tests/TbfTest: reproduce buggy corner case: MS with TBFs on 2 TRXs
Add a test which showcases a scenario where the PCU ends up with 1
GprsMs object holding a DL-TBF in a weird condition half in one TRX and
half in other due to ms_merge().
This test (slightly adapted) used to cause a crash in osmo-pcu.git
586ddda9bc09d60f2d491158de843825cb7c876a (a few versions behind current
master).
