Change references to qemu in Coreboot-v2 calls to qemu-x86.

The patch was followed by these svn commands:

svn mv targets/emulation/qemu-i386/ targets/emulation/qemu-x86
svn mv --force targets/emulation/qemu-i386/ targets/emulation/qemu-x86
svn mv --force src/mainboard/emulation/qemu-i386/
src/mainboard/emulation/qemu-x86
svn mv --force src/cpu/emulation/qemu-i386/ src/cpu/emulation/qemu-x86
