[PATCH] fix: improve check for availability of compat arch

[Adriaan Schmidt <adriaan.schmidt@siemens.com>]

follow-up to 3aa4d3832ccb2271e850a8245cb45ad40e3da366

The check, whether compat can be built needs to also ensure that we
actually have a compat arch for our DISTRO_ARCH. There is a helper
function in the compat class for this now.

Sorry, I was slow to send an updated patch, rebasing the essential
packages feature onto v4 of the multiarch series.
