Emmanuel Gil Peyrot a137dd5f79 xwayland: Use memfd_create() when available 
This (so-far) Linux-only API lets users create file descriptors purely
in memory, without any backing file on the filesystem and the race
condition which could ensue when unlink()ing it.

It also allows seals to be placed on the file, ensuring to every other
process that we won’t be allowed to shrink the contents, potentially
causing a SIGBUS when they try reading it.

This patch is best viewed with the -w option of git log -p.

This is a port of this commit from Weston:
deae98ef45

Fixes #848.
