Fix out-of-tree build of numa_helper

This patch adds an include search path to the CPPFLAGS for
numa_helper.c to locate header files generated earlier in the build
process for out-of-tree builds.

The linux_syscall_numbers.h header file is generated during the
build process into the build directory. The CPPFLAGS to build
testcases/kernel/lib/numa_helper.c however don't provide the build
directory as an include search path.
