Running vgabios during resume from S3 on QEMU by default

Run vgabios during resume from S3 by default on QEMU. QEMU
still able to modify SeaBIOS behavior if it wishes so by providing
etc/s3-resume-vga-init file. With QEMU emulated vga cards this behaviour
is desirable otherwise console becomes unusable with Linux guests after
resume. Since we control vgabios source we can be sure that running it
on resume from S3 is safe.
