ci/ci: use the same package manager for all builds

Currently we are using rpm in qcom-distro and ipk in nodistro.
This causes non-determinism between distributions and has implications in
build performance. Basically, we can't use packages in sstate-cache from
distro1 in distro2, and everything has to be recompiled.
