Cirrus: Force runc use in F30

Suspect crun might be sneaking in during VM image build via podman RPM
dependency.  Add it to the removal list when building, then also force
use of runc at runtime in F30.

Also quote all true/false vars to force them as strings instead of
booleans (which will become capitalized)
