LU-11176 systemd: use univeral path for modprobe

The program modprobe is not the same on all platforms. On RHEL
systems it is located in /usr/sbin. For Ubuntu/Debian which is
busybox based /sbin/modprobe is a symlink to /bin/kmod. On all
platforms to keep some sort of standard a symlink for modprobe
exist in /sbin. Update the lnet.service script to use the hard
patch /sbin/modprobe
