Linux: Add memfd_create system call wrapper
The system call is somewhat obscure because it is closely related to file descriptor sealing. However, it is also the recommended way to create alias mappings, which is why it has more general use. No emulation is provided. Except for the name of the /proc/self/fd links, it would be possible to implement an approximation using O_TMPFILE and tmpfs, but this does not appear to be worth the added complexity.
