......................................................................

Add TC_pcu_oml_alert() for testing PCU-originated OML alerts

As we don't yet speak OML directly from the TTCN3 test suite,
this requires a currently "RFC/WIP" state patch turning OML
Failure Event Reports into CTRL TRAP on the BSC, see
https://gerrit.osmocom.org/#/c/osmo-bsc/+/14177
