[PATCH v2] hw/display: load the correct ROM file for isa-vga device

[Liav Albani]

Apparently QEMU didn't load the correct ROM file when using the isa-vga
device on my development machine, which resulted in a display waiting to
be initialized by a guest OS kernel. With this fix, SeaBIOS is able to
print vital data to a text mode console during boot, which is useful in
case of failing to continue booting.

The build name of the vgabios.bin is changed too, to vgabios-isavga.bin
to ensure we always have that file when QEMU is installed as a package
or compiled from source.
