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.
