Subject: [PATCH] selftests/landlock: fix broken include of linux/landlock.h

Revert part of the earlier changes to fix the kselftest build when
using a sub-directory from the top of the tree as this broke the
landlock test build as a side-effect when building with "make -C
tools/testing/selftests/landlock".

Reported-by: Mickaël Salaün <mic@...ikod.net>
Fixes: a917dd94b832 ("selftests/landlock: drop deprecated headers dependency")
Fixes: f2745dc0ba3d ("selftests: stop using KSFT_KHDR_INSTALL")
