packaging: qemu-snp-experimental: support host kernel with gmem

Browse Source 
This is required to allow creation of SNP coco on host kernel
(e.g. https://github.com/AMDESE/linux ,branch:snp-host-latest)
supporting guest private memory for SNP using gmem.

Note: This qemu does not work if the host kernel does not support
gmem/UPM.

Fixes: #9092
