EX-3342 tests: correct Lustre version in test skip checks

Many patches land to the EXAScaler branches as ports from
other branches.  Sometimes the tests that are included with
the ported patches check the version of Lustre to ensure
that the feature it tests exists in this version of Lustre.
These version values are not always changed when patches
are ported from one branch to another.

Change Lustre test suite version checks to be relative to
this branch.
