improve/fix f_tc_mo_setup_dtmf_dup

- Fix error log for a missing final DTMF.

- Instead of code dup to establish a call, use f_mo_call_establish().  This
  will make the test benefit from changes to f_mo_call_establish() (which will
  soon come up to accomodate changes in osmo-msc's codec negotiation).

- Instead of hardcoding the expected N_SD counter values to detect DTAP
  duplicates, use f_bssmap_last_n_sd() and f_next_n_sd(), so that the N_SD
  counter is correct regardless of how many DTAP were sent in
  f_mo_call_establish().

- Instead of hardcoding a correct N_SD in the end, use skip_seq_patching ==
  false, so that the ttcn DTAP correctly tracks N_SD for subsequent call
  release messages.

- Release the call.
