[OE-core] [PATCH 3/3] qemu: switch to '-vga std' emulated hardware from vmware/cirrus for x86/mips

This is the qemu default since qemu 2.2, is generally supported better,
and is recommended by upstream. It also has already been in use for arm/risc
and ovmf.

Additional information:
https://bugzilla.yoctoproject.org/show_bug.cgi?id=13466
https://www.kraxel.org/blog/2014/10/qemu-using-cirrus-considered-harmful/

'-vga virtio' emulated hardware remains in use when virgl is enabled via a runqemu override.
