ci: Make container environment available to scripts

For container images targeted at cross-building, we bake a small
amount of architecture-specific information in the environment so
that builds can work as expected without requiring additional work
from the user; unfortunately this information got lost as soon as
we called sudo. Explicitly allow it.
