Add chromeos_qemu_recovery_config

This CL adds a new target chromeos_qemu_recovery_config that, as its name
suggests, supports qemu emulation.

It would let you emulate u-boot image:
$ qemu-system-arm -M versatilepb -cpu cortex-a9 -kernel u-boot.bin

Note: qemu 0.12.5 is known to crash; 0.13.50 or newer should work fine.

BUG=None
TEST=Build target chromeos_qemu_recovery_config and emulate successfully
