IMHO adding other flags to KHDR_INCLUDES is not the right solution, it
conflates unrelated things. Some tests may want the kernel headers but
not _GNU_SOURCE, or vice versa.
Adding a separate define for "standard kselftest flags" would be
preferable, and then something like __SANE_USERSPACE_TYPES__ would make
sense being added to it.
