    ndp tests: Fix an assertion in ndp_prefix_lifetime_extend
    
    Here we have two interface addresses sharing a v6 prefix with finite
    lifetime.  The intent was to make sure that adding the second address
    didn't cause the prefix's valid lifetime to drop from 20s to 10s, but of
    course, while the test is running it may drop from 20s to 19s, causing
    the test to fail spuriously.  Relax the check a bit to avoid this.
