Support custom ulimit settings in *_base scripts.
From a customer:
I do have suspicion that the script refresh_P4ROOT_from_offline_db.sh,
which is part of SDP, is restarting the p4d server and then omits to
start it with the settings (ulimit -S -c unlimited > /dev/null 2>&1)
in /etc/profile.
Per @giles:
What is the right way to propagate such setting into SDP environment
when doing the refresh_P4ROOT_from_offline_db.sh so this doesn't happen
again and we can capture the core files?
