At the point of saving the bootcmd for the second stage of the install
process we want to use the variable value, not the variable name
since this variable doesn't exist after the environment is reset.

The USB and SD installers are U-Boot scripts that are practically
identical.
Merge them into a single template with a couple of machine variables that
determine the default device index in U-Boot for the USB or the microSD
card.
Do dynamic substitutions to create the two installers out of the template.
