Xiaoyao Li 75e2cb1441 hostmem/shm: Allow shm memory backend serve as shared memory for coco-VMs ...

shm can surely serve as the shared memory for coco-VMs. But currently it
doesn't check the backend->guest_memfd to pass down the RAM_GUEST_MEMFD
flag. It leads to failure when creating coco-VMs (e.g., TDX guest) which
require private mmeory.

Set and pass down RAM_GUEST_MEMFD when backend->guest_memfd is true, to
allow shm memory backend serve as shared memory for coco-VMs.
