selftests/bpf: Clean up user_ringbuf, cgrp_kfunc, kfunc_dynptr_param tests
Clean up user_ringbuf, cgrp_kfunc, and kfunc_dynptr_param tests to use
the generic verification tester for checking verifier rejections.
The generic verification tester uses btf_decl_tag-based annotations
for verifying that the tests fail with the expected log messages.
