seccomp_bpf failed on tests 47 global.user_notification_filter_empty and 48 global.user_notification_filter_empty_threaded when it's tested on updated kernel but with old kernel headers. Because old kernel headers don't have definition of macro __NR_clone3 which is required for these two tests. Since under selftests/, we can install headers once for all tests (the default INSTALL_HDR_PATH is usr/include), fix it by adding usr/include to the list of directories to be searched. Use "-isystem" to indicate it's a system directory as the real kernel headers directories are.

"../../../../usr/include/" directory doesn't have header files if different output directory is used for kselftests build like "make -C tools/tests/selftest O=build". Can you try adding recently added variable, KHDR_INCLUDES here which makes this kind of headers inclusion easy and correct for other build combinations as well?
