Pau suggested in the related issue that we try to write the bts logs into tmpfs, instead of directly to ext4. This seems to cause the slow downs, which then result in clock skew errors.
Import this script from osmo-ci dfa9fcca ("scripts/wrapper_core_bt_on_error: new script"), so it can be used in ttcn3-asterisk-ims-ue-test in a follow-up patch.
ttcn3-asterisk-ims-ue-test: show trace on coredump
Use wrapper_core_bt_on_error.sh to show a backtrace in case asterisk crashes and a coredump is generated. Set CWD to /data, so the core and core.backtrace files end up in the jenkins artifacts.
The result looks like this (forced a segfault in main() to test this): $ cat asterisk-ipv4/core.backtrace [New LWP 18] [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

osmo-ns-master: drop python3-osmopy-utils / --enable-external-tests
--enable-external-tests requires python3-osmopy-utils, however this package is no longer available for debian:10. We're not running tests, so it's not really needed. Removing it fixes ttcn3-ns-test-fr.
