Previous code relied on abort() switching sigaction to SIG_FDL +
retriggering SIGABRT in case the signal handler returns, which would
then generate the coredump + terminate the process.
However, if a SIGABRT is received from somewhere else (kill -SIGABRT),
then the process would print the talloc report and continue running,
which is not desired.

Fixes: OS#4865
* is_config_node is deprecated, so don't set it
* go_parent_cb is only used if we want to do special stuff upon exiting
a node, in osmo-sgsn and gtphub only osmo_ss7_vty_go_parent() needs to
be called
