[LU-7573] rmmod command is missing the -w option

Description

The rmmod command in the most recent linux versions we support has no -w option. Since some of our tests use this option those tests fail.

Currently the only linux versions impacted by this problem are RHEL 7.2 and SLES 12. Over time there will likely be more.

The only test known to hit this problem for sure is sanity, test 60a. The script run-llog.sh called by this test uses 'rmmod -vw'. There may be others not detected yet.

Until a better fix is developed to avoid the use of the missing option I will work up a patch to just skip the test in cases where there is no -w option available.
