Tor 0.3.3.1-alpha resumes allowing RunAsDaemon=1 with relative DataDirectory

In 0.3.2.1-alpha we fixed #22731 (moved) (in commit 6fea44c6): we started refusing to start if RunAsDaemon is set and also any of a variety of config options are set to a relative value.

And then in 0.3.3.1-alpha we did commit 192be006, which split the original options->DataDirectory into a new DataDirectory_option variable.

But warn_about_relative_paths() continues to look at

  n += warn_if_option_path_is_relative("DataDirectory",options->DataDirectory);

and that function is called near the top of options_validate() -- before we call validate_data_directories() which is what populates options->DataDirectory.
