[PATCH 0/5] cleanups, fixes, and progress towards avoiding "make headers"

Eventually, once the build succeeds on a sufficiently old distro, the
idea is to delete $(KHDR_INCLUDES) from the selftests/mm build, and then
after that, from selftests/lib.mk and all of the other selftest builds.

For now, this series merely achieves a clean build of selftests/mm on a
not-so-old distro: Ubuntu 23.04:

1. Add __NR_mseal.

2. Add fs.h, taken as usual from a snapshot of ./usr/include/linux/fs.h
after running "make headers". This is how we have agreed to do this sort
of thing, see [1].

3. Add a few selected prctl.h values that the ksm and mdwe tests require.

header files")
