O-Subject: [RHEL-7.4 qemu-kvm PATCH 6/9] iotests: Fix test 039
Bugzilla: 1427176

Test 039 used qemu-io -c abort for simulating a qemu crash; however,
abort() generally results in a core dump and ulimit -c 0 is no reliable
way of preventing that. Use "sigraise $(kill -l KILL)" instead to have
it crash without a core dump.
