samples/landlock: Add clang-format exceptions

commit 9805a722db071e1772b80e6e0ff33f35355639ac upstream.

In preparation to a following commit, add clang-format on and
clang-format off stanzas around constant definitions.  This enables to
keep aligned values, which is much more readable than packed
definitions.
