PCU: Tests for the BSS/PCU side NS/BSSGP implementations

The existing (unused) PCU_Tests are operating on top of a NS + BSSGP
emulation, i.e. they're aimed at testing higher protocol layers.  Also,
they required BTS+BSC to run next to the PCU.

The new PCU_Tests_RAW introduced in this patch are the exact opposite:
* they test the PCU alone (attach to PCUIF and Gb interface)
* they don't require BTS or BSC to run
* they don't use NS + BSSGP emulation but raw NS/BSSGP frames to
  test the very NS/BSSGP implementation inside of OsmoPCU.
