mncc: protect against non responsive MNCC during setup

When the SETUP is sent throgh the MNCC socket to the remote entity
(e.g. osmo-sip-connector) we expect an almost immediate response that
tells us if the call was accepted or rejected. However, there may be
cases where the remote entity becomes unresponsive. In those cases the
MNCC handling on the msc side would hang. Lets schedule a timer to make
sure that osmo-msc can not hang if the setup is not answered.

- Add timeout in gsm48_cc_rx_setup(), hard-clear the call when the
  timeout expires (CLEAR COMMAND to BSC)
