selftests: bpf: Update kfunc_param_nullable test for new error message



With trusted args now being the default, the NULL pointer check runs
before type-specific validation. Update test3 to expect the new error
message "Possibly NULL pointer passed to trusted arg0" instead of the
old dynptr-specific error message.
