[Bug?] quickemu windows-server default enable 9p

[yffengdong]

I use windows-server see shell file has 9p, but windows not support 9p now.

...
-fsdev local,id=fsdev0,path=/home/tag/Public,security_model=mapped-xattr \
-device virtio-9p-pci,fsdev=fsdev0,mount_tag=Public-tag \
...

Add support for windows languages & windows server.

if [ "${guest_os}" != "windows" ] || [ "${guest_os}" == "windows-server" ] && [ -n "${PUBLIC}" ]; then
