selftests/landlock: Format with clang-format
Let's follow a consistent and documented coding style.  Everything may
not be to our liking but it is better than tacit knowledge.  Moreover,
this will help maintain style consistency between different developers.

This contains only whitespace changes.

Automatically formatted with:
clang-format-14 -i tools/testing/selftests/landlock/*.[ch]

selftests/landlock: Add clang-format exceptions
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 .

5a69d33b3e selftests/landlock: remove ARRAY_SIZE define from common.h
ARRAY_SIZE is defined in several selftests. Remove definitions from
individual test files and include header file for the define instead.
ARRAY_SIZE define is added in a separate patch to prepare for this
change.

Remove ARRAY_SIZE from common.h and pickup the one defined in
kselftest.h.

e1199815b4 selftests/landlock: Add user space tests
Test all Landlock system calls, ptrace hooks semantic and filesystem
access-control with multiple layouts.

Test coverage for security/landlock/ is 93.6% of lines.  The code not
covered only deals with internal kernel errors (e.g. memory allocation)
and race conditions.
