Acceptance tests: use avocado tags for machine type

The same way the arch tag is being used as a fallback for the arch
parameter, let's do the same for QEMU's machine and avoid some boiler

This is now possible because, since Avocado 72.0, it's possible to use
tags with names that match the machine types on QEMU.
