Subject: [PATCH] lib.sh: AArch64: Use VGA video mode for guests

On AArch64, there is no Cirrus video, so use VGA mode instead.
For now, we install vgabios package no matter the arch, although
it is only used on AArch64.

On Debian systems, also fix a missing link for vgabios-stdvga.bin.
Based on previous Armband work from [1].
