Use tools/include/uapi/ files instead. These are obtained by taking a snapshot: run "make headers" at the top level, then copy the desired header file into the appropriate subdir in tools/uapi/. This was discussed and solved in [1]. However, even before copying any additional files there, there are already quite a few in tools/include/uapi already. And these will immediately fix a number of selftests/mm build failures. So this patch: a) Adds TOOLS_INCLUDES to selftests/lib.mk, so that all selftests can immediately and easily include the snapshotted header files. b) Uses $(TOOLS_INCLUDES) in the selftests/mm build. On today's Arch Linux, this already fixes all build errors except for a few userfaultfd.h (those will be addressed in a subsequent patch).
