Today we reset the suite counter as part of the suite cleanup,
called from the module exit callback, but it might not work that
well as one can try to collect results without unloading a previous
test (either unintentionally or due to dependencies).

The kselftest-merge target walks all kselftests configs, and merges
them. However, builtin does not have precedence over modules. This
breaks some of the tests, e.g.:
