The selftests/mm build isn't exactly "broken", according to the current
documentation, which still claims that one must run "make headers",
before building the kselftests. However, according to the new plan to
get rid of that requirement [1], they are future-broken: attempting to
build selftests/mm *without* first running "make headers" will fail due
to not finding __NR_mseal.
Therefore, include asm-generic/unistd.h, which has all of the system
call numbers that are needed, abstracted across the various CPU arches.

header files")
