The "also fix" indicates a second logical change bundled in. Please split
the minor cleanup fixes (blank line in memfd_create01.c, trailing semicolon
in CHECK_MFD_HAS_SEALS) into a separate commit so each patch contains
exactly one logical change.

This fix is independent of the sys_memfd_create() move — separate commit.

Pre-existing issues noticed in the surrounding code (not introduced
by this patch):

- include/lapi/memfd.h (pre-patch) — file relied on callers to pull in
  tst_test.h and lapi/syscalls.h transitively; now correctly self-contained.
