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, add __NR_mseal, to a new mseal_helpers.h file. That file is
small right now, but subsequent patches will add a lot more content to
it.

header files")
