LU-13063 tests: stop running sanity test 411

sanity test 411 hits a kernel bug for RHEL 8.1.  Since this
is an issue with the kernel and not Lustre, let's stop
running this test until the kernel is patched.  Thus, we
need to add sanity test 411 to the ALWAYS_EXCEPT list.

Also change the ALWAYS_EXCEPT condition for test smoke for
lnet-selftest to be based on kernel version and not
architecture, so that the custom test for this patch can
pass.

This patch is back-ported from the following one:
