Rockbox as an application: add get_user_file_path().

For RaaA it evaluates user paths at runtime. For everything but codecs/plugins it will give the path under $HOME/.config/rockbox.org if write access is needed or if the file/folder in question exists there (otherwise it gives /usr/local/share/rockbox).
This allows for installing themes under $HOME as well as having config.cfg and other important files there while installing the application (and default themes) under /usr/local.

On the DAPs it's a no-op, returing /.rockbox directly.

Not converted to use get_user_file_path() are plugins themselves, because RaaA doesn't build plugins yet.
