landlock: Add clang-format exceptions

commit 6cc2df8e3a3967e7c13a424f87f6efb1d4a62d80 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.
