cros_bundle_firmware: Implement the boot source machine param

This allows us to select the SPL boot source.

BUG=chromium-os:28394
TEST=manual:
$ cros_bundle_firmware -b daisy -w sd: -B usb
See that it boots from SD, then goes into USB download mode instead
of booting U-Boot from SD
$ sudo smdk-usbdl -a 0x43e00000 -f out/u-boot-from-image.bin
See that it boots the U-Boot thus downloaded
