test: add ripemd160 to test framework modules list

Currently test runner doesn't execute the unit tests of the ripemd160
module, so add it to the list. All other framework modules that contain
unit tests are included, as can be easily checked via
`git grep unittest.TestCase ./test/functional/test_framework/`

This is a late follow-up to PR #23716 (commit
ad3e9e1).
