a917dd94b8 selftests/landlock: drop deprecated headers dependency 
The khdr make target has been removed, so drop it from the landlock
Makefile dependencies as well as related include paths that are
standard for headers in the kernel tree.

f2745dc0ba selftests: stop using KSFT_KHDR_INSTALL 
Stop using the KSFT_KHDR_INSTALL flag as installing the kernel headers
from the kselftest Makefile is causing some issues.  Instead, rely on
the headers to be installed directly by the top-level Makefile
"headers_install" make target prior to building kselftest.

cb542c66f3 selftests: landlock: Add the uapi headers include variable 
Out of tree build of this test fails if relative path of the output
directory is specified. Add the KHDR_INCLUDES to correctly reach the
headers.

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.
