build,json: fixup missing arch_packages

Fix 7f4c2b1a "build,json: fix duplicates in default_packages" which
removed duplicate default packages but also removed the package
architecture from the profiles.json.

If DUMP=1 is set, the `ARCH_PACKAGES` is no longer exported and
therefore empty. Fix this by running make twice, once with DUMP=1 and
once without.
