[PATCH qemu-server v3 2/2] qemuserver: make vga model mapping architecture-aware

[Kaiyang Wu <wukaiyang2003@gmail.com>]

Fix virtio-gpu not being available on aarch64.

QEMU only provides the non-VGA variant of virtio-gpu-gl on aarch64.
Add 'map_vga_model' subroutine to map VGA models to correct device
names on different architectures accordingly, replacing the old 'vga_map'
look up method.
