LU-3962 utils: improve names of iokit tools

Some of the names of scripts in the lustre-iokit package are very
generic and may easily cause confusion for users, or conflict with
other installations.  Rename them to more unique names and update
the files that reference them.

Fix whitespace in renamed files.
