test: Always install dpkg into our tests, regardless of MA

Even if we only configure a single architecture, install dpkg, so
dpkg can assert multi arch correctly. This also has the nice side
effect of making single architecture and multiple architecture
test cases more uniform.

This fixes a regression from f878d3a862128bc1385616751ae1d78246b1bd01
("test: Assert multi-arch in the chroot").
