testenv: osmo_dev: remove unused limit_section arg

Remove the unused limit_section argument in testenv.osmo_dev.make(). The
idea was to use osmo-dev to build programs where no packages are
available when using --binary-packages, but this didn't work because
when using --binary-packages, we must install all package dependencies
from the binary repository (so testing nightly / latest use the expected
library versions). Nowadays this use case is handled by
podman_install.from_source_* functions without using osmo-dev.
