Makefile: use variables for platforms instead of repeating platform numbers 

Create a variable called BUILD_PLATFORMS that lists the various pi images
to build. This keeps the platform list in one place in the makefile, rather
than sprinkled and repeated throughout multiple dependency and build lines.

When a platform is added (ie, the pi4) or removed, it won't touch multiple
rules and obscure other changes. This uses gmake-specific addprefix and
addsuffix.
