Use 2 separate variables of types int and unsigned long long instead of

By allowing the filter_glob parameter to be written to, it's possible to
tweak the testsuites that will be executed on new module loads. This
makes it easier to run specific tests without having to reload kunit and
provides a way to filter tests on real HW even if kunit is builtin.

If an integer's type has x bits, shifting the integer left by x or more
is undefined behavior.
This can happen in the rotate function when attempting to do a rotation
