[PATCH v2 1/2] scripts: generate_rust_analyzer.py: add missing include_dirs

Commit 8c4555ccc55c ("scripts: add `generate_rust_analyzer.py`")
specified OBJTREE for the bindings crate, and `source.include_dirs` for
the kernel crate, likely in an attempt to support out-of-source builds
for those crates where the generated files reside in `objtree` rather
than `srctree`. This was insufficient because both bits of configuration
are required for each crate; the result is that rust-analyzer is unable
to resolve generated files for either crate in an out-of-source build.

Add the missing bits to improve the developer experience.
