Restore previous behavior of 'make regen-cases' (#106541) 

When running 'make regen-cases' just to check whether anything changed,
it's annoying that even if nothing changes, the output files are touched,
causing an expensiv rebuild of _bootstrap_python and anything it creates.

So use  consistently for all output files.
