ui/surface: allocate shared memory on !win32
Use qemu_memfd_alloc() to allocate the display surface memory, which
will fallback on tmpfile/mmap() on systems without memfd, and allow to
share the display with other processes.
This is similar to how display memory is allocated on win32 since commit
09b4c198 ("console/win32: allocate shareable display surface").
