On the environment hard limit of coredump is set to zero, coredump test
script will fail since the system does not generate coredump.
To avoid such issue, set ulimit -c 0 before generating SEGV on the script.
Note that scylla-server.service can generate coredump even ulimit -c 0
because we set LimitCORE=infinity on its systemd unit file.
Fixes #8238
Closes #8245
