[buildroot] Implement an ARCH_PACKAGES variable which defaults to BOARD but can be overridden on a per-subtarget basis.

This is intended for targets such as adm5120 and malta which support both big and little endianess and will replace
the target specific exceptions in package-defaults and Image Builder.
