gitlab-ci: Avoid to re-run "configure" in the device-crash-test jobs

After "make check-venv" had been added to these jobs, they started
to re-run "configure" each time since our logic in the makefile
thinks that some files are out of date here. Avoid it with the same
trick that we are using in buildtest-template.yml already by disabling
the up-to-date check via NINJA=":".
