[LTP] [PATCH] runpwtests03: fix for module name retrieval

[Po-Hsu Lin]

The -l flag for modprobe has been deprecated in newer packages.
This will induce some noise during the execution:
    modprobe: invalid option -- 'l'

And making the "Loading and Unloading of governor kernel modules" test
not doing module load / unload operations.

Fix this by using the find command to retrieve module names instead.
