[CI] Fix missing parameters transfer from ibd.sh to bitcoind

Summary:
The `ibd.sh` script is expected to transfer its arguments to `bitcoind`.
This allow to set the `assumevalid` and `checkpoints` options as needed.

Test Plan:
  ./contrib/teamcity/ibd.sh -assumevalid=0 -checkpoints=0
Check in the output that bitcoind is started with these arguments.
