LU-6051 utils: Remove incorrect request for getstripe help

The option flag for stripe-size in the getstripe command was changed
in Lustre 1.8.  To detect the correct flag to use, the help was
parsed.  However, the help was incorrectly invoked by using the
"--help" option, instead of the correct "lfs help getstripe".
Since interoperability with 1.8 is no longer needed, the incorrect
code is removed and the correct flag is hard-coded.
