CI: refine tshark capture filters

Browse Source 
The CI pcaps are too large if we have large data traffic, as they
include all the GTP capture (they contain basically the data that we
send in the tests). This commit reduces this:
- in the RAN: capture only S1AP (port 36412), X2AP (36422), NGAP (38412)
  traffic
- in the CN: exclude GTP traffic (port 2152)
