[Pacemaker] wchih user's path is called from getenv("PATH")/external.c

sorry, my explanation was not clear.
I want to use the specify "ipmitool" command, like /tmp/ipmitool not
/usr/bin/ipmitool.
external/ipmi get it as `which ipmitool`,
so I tried to add its path in root user's path,
but it was ignored.

Thanks,
Junko
