Subject: [PATCH 5.18 772/879] selftests/landlock: Add clang-format exceptions

From: Mickaël Salaün <mic@...ikod.net>

commit 4598d9abf4215e1e371a35683350d50122793c80 upstream.

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

Add other clang-format exceptions for FIXTURE() and
FIXTURE_VARIANT_ADD() declarations to force space before open brace,
which is reported by checkpatch.pl .
