[LU-1083] tunefs.lustre generates incorrect message when PATH doesn't include /sbin

Description

If I execute tunefs.lustre on the MDS/MGS or OSSes without /sbin in my PATH, it displays an error message stating the device has not been formatted with mkfs.lustre. This is incorrect. As soon as I add /sbin to my PATH, tunefs.lustre works fine.

pmds1:~$ sudo /usr/sbin/tunefs.lustre --print /dev/mapper/mpath0
checking for existing Lustre data: not found
tunefs.lustre FATAL: Device /dev/mapper/mpath0 has not been formatted with mkfs.lustre
tunefs.lustre: exiting with 19 (No such device)

pmds1:~$ export PATH=$PATH:/sbin

pmds1:~$ sudo /usr/sbin/tunefs.lustre --print /dev/mapper/mpath0
checking for existing Lustre data: found CONFIGS/mountdata
