clearfog: fancy flashing
There's no need to use emergency.target anymore, the `run usbboot` (or
its longer equivalent if we're in Marvell's factory U-Boot) will perform
the flashing automatically.
It's a bit complex because one has to wait for /dev/sda1 to appear
first. That needs udev to be running. Then one has to mount the image.
In the end I decided to go for a unit generator because it is not clear
whether the actual .device unit is just `dev-sda1.unit` or something
much more interesting like `sys-devices-platform-soc-soc:internal\x2dregs-f10f8000.usb3-usb2-2\x2d1-2\x2d1:1.0-host4-target4:0:0-4:0:0:0-block-sda-sda1.device`.
