If memfd_create is unavailable, try using O_TMPFILE via
tempfile.TemporaryFile.
MacOS has no memfd_create or O_TMPFILE. Unforunately, using
/dev/fd/{FD} as an argument to dlopen doesn't work either after
unlinking from the file system (see
https://gist.github.com/heiner/5179ccaef983b318c1fc451d7efbe95d#file-tmp_memfs_mac-py).
So let's copy instead and hope vardir gets properly deleted at some
point.
