docs: conf.py: get rid of load_config.py

The code here was meant to handle 3 functions:
1. allow having a separate conf.py file, per subdir;
2. generate a list of latex documents.
3. set "subproject" tag if SPHINXDIRS points to a subdir.

We don't have (1) anymore, and (3) is now properly handled
entirely inside conf.py.

So, only (3) is still needed, and this is a single-line change
at conf.py.

So, drop it, moving the remaining code to conf.py.

While here, drop a duplicated $(RUSTDOC) command-line argument.
