linux_memfd_create was commited in https://reviews.freebsd.org/rS362769. Not sure why it wasn't backported.

There is the `enable-memfd` configuration parameter, it doesn't look deprecated to me.

I was unsure of the feasibility of backporting some parts of the file sealing due to possible KPI changes, so neither that nor shm_open2 have been backported.

I think it could be closed now, we do not MFC of Linuxulator to the stable/12 branch an so one. ok?
For inotify we have another PR.
