LU-11596 tests: disable several sanity sub-tests for ARM

The following sanity sub-tests are consistently failing
on ARM clients:
- 42d, 42e, 63a, 63b, 64a, 64b and 64c (LU-11596)
- 45 (LU-11671)
- 101c (LU-11665)
- 103a (LU-11594)
- 317 (LU-11667)

This patch adds them to ALWAYS_EXCEPT list to exclude
the failures, so as to make ARM client test session pass.

They will be removed from the list and re-enabled in the
patches that fix the failures.

Test-Parameters: trivial
