tests: Re-add the ability to generate core files with topotests

Browse Source 
Somewhere along the line core-files stopped being generated
with the running of the topotests.  With this change we now
see this:

sharpd@eva /t/topotests> find . -name '*.dmp' -print
./ospfv3_basic_functionality.test_ospfv3_asbr_summary_topo1/r0/ospf6d_core-sig_6-pid_430478.dmp
sharpd@eva /t/topotests> sudo gdb /usr/lib/frr/ospf6d ./ospfv3_basic_functionality.test_ospfv3_asbr_summary_topo1/r0/ospf6d_core-sig_6-pid_430478.dmp
