graphics/qt5-wayland: use memfd_create() on 13+

On 13+, the memfd_create() syscall can create anonymous shared-
memory areas that behaves like a file. This is used upstream
(not in Qt, but in KDE) when possible. Use it when relevant,
since it avoids creating temporary files.

While here, freshen-up the other patches.
