Revert "x86: Switch QEMU over to use the bochs driver"

Unfortunately the bochs driver does not currently work with distros.
It causes a hang between grub menu selection and the OS displaying
something.

Preliminary investigation shows that GRUB does not jump to the kernel
at all.

This reproduces reliably.

This reverts commit b8956425d525c3c25fd218f252f89a5e44df6a9f.
