Planning to use memfd_create() in flatpak and rpm-ostree, which both use bubblewrap, and want to pass read-only data via file descriptor to the container. Passing via `O_TMPFILE` requires `O_RDWR` (read and write), and passing via a pipe would require buffering. The systemd `missing.h` has grown enormously; I only cherry-picked the bits for memfd.
