            selinux-testsuite: avoid unsafe tweaks

Replacing kernel version occurences is problematic when different tests
have the same bounding kernel version, as is true for current upstream.
Therefore, replace it with adding "force_tests" list that works
similarly to the existing "exclude_tests" list, but forces execution of
the tests instead of excluding them.
