[PATCH] verification/rvgen: Use .old instead of .bak for kunit backup files

The rvgen kunit command generates .bak backup files and these can be
checked in for selftests (make check). Clean targets like make disclean
remove such files, leaving the tree dirty.

Switch to .old to preserve a clean tree after make disclean.
