You shouldn't run any tests like this at build time.

For autopkgtests, if you set the needs-root and isolation-machine
restrictions then the tests will run as root on a VM.  But currently
neither salsa-ci nor ci.debian.net implements this, so those tests will
be skipped.

Another option in autopkgtests is to depend on qemu and start the VM
yourself.  This is not easy to do, but I implemented it for initramfs-
tools.
