It is wrong to include unprocessed user header files directly. They are processed to "<source_tree>/usr/include" by running "make headers" and they are included in selftests by kselftest makefiles automatically with help of KHDR_INCLUDES variable. These headers should always bulilt first before building kselftests.

Remove all defines which aren't needed after correctly including the kernel header files.
