fix(base): install QEMU for ‹RUN› in build action

It appears that for building multi-arch images, you need to have some
layer of emulation installed, i.e., QEMU, just to be able to execute the
‹RUN› commands during the image build as the container image of different
architecture is still run on the host platform (therefore the execution
needs to be emulated).
